These sites immediately come up as unavailable server:

  • Toshiba 32RL853B - many features not available firmware update

    So, after downloading the drivers to see there is no USB option to upgrade my Regza 32 RL853B and several network download failures trying to upgrade the firmware on the TV, because overair is greyed out.

    I finally got a fast enough connection (internet is pathetic where we live), to download the upgrade.
    When it was installed, I would expect the Youtube XL to be replaced by something that works.

    I even thought I might be lucky enough to get Netflix or some these applications added to the available software.

    I expected too much?
    To be honest, it seems to be absolutely no change!

    What have I waited for this upgrade?

  • All of a sudden I can't copy and paste copy/cut/paste is not available in Mozillia firefox. Never seen that before

    I have never seen this before when I try to copy and paste, I get a
    ' Copy/cut/paste is not available in Mozilla and firefox. Do you want more information about this issue? "
    I copied and pasted hundreds of times before with Mozilla and firefox. This just happened all of a sudden.
    When I go to find more information on this issue, it gives a long explanation I can't follow.
    That's happened?

    When you click the link, the page immediately said you that you can not copy, or which occurs as soon as you click on copy the location of the link?

    If it immediately, you can pass a parameter in Firefox that should prevent the normal context menu blocking sites. Here's how you would do that:

    (1) in a new tab, type or paste Subject: config in the address bar and press ENTER. Click on the button promising to be careful.

    (2) in the search above the list box, type or paste the context and make a pause so that the list is filtered

    (3) double-click the preference dom.event.contextmenu.enabled from true to false.

    This setting has a complication: right-click on Google Maps and other sites that have their own menu, menu Firefox then crashes the site menu. To clear the menu of Firefox so you can access the site button menu tap ESC or the ALT key once (but sometimes Esc deletes both).

  • 14.0.1 Firefox does not not on many Sites

    I have Firefox 14.0.1 and use a Mac. Recently, I visited sites and some pages are blank. When I use Omniweb or another browser, it is not empty. It's extremely frustrating. For example, this page is completely blank, (like white) for me on Firefox, but on other browsers I see very well.
    http://www.tastingtable.com/entry_detail/chefs_recipes/9755?allow
    This happens on many sites. On some pages on some sites, I see one of the sites own warnings as "Oops, this page has been moved" but when I copy and paste the same url in another browser, it loads perfectly. It is either completely empty or doesn't load properly and this only happens with Firefox.

    I have cleared my cache and cookies and I have "no proxy" checked. Help, please!

    You can try to reset all preferences

    Start Firefox in Safe Mode to check if one of the extensions or if hardware acceleration is the cause of the problem (switch to the DEFAULT theme: Firefox/tools > Modules > appearance/themes).

    Simply because Apple makes the promotion of iBooks does not necessarily that they are available in all locations.

  • HP Update site is not available!

    Hello! I'm new to the forum!

    I have seen problems reciving and connection to the HP drivers Update site. I am from Croatia, Zagreb and I checked with several of my friends and co-workers who have the problem of sam! When I select my laptop HP Probook 470 G2 in the product range I revice this error:

  • Graphics/video card not available from Nvidia Web site update.

    Greetings,

    I need to update the video card for an hp Pavilion dv6704nr w / videocard geforce 7150 m/nforce 630 m, running windows 7. I was told during my visit to Nvidia, I have go the manufacturer of my system to get the update.

    It seems that if HP is going to force people to go there to get the update of the site, they should make available and for all major browsers. I know that my system came with Vista, but who knew at the time a program what Vista crap. HP offered here windows7 customers instead once he's out, but once you do this, HP will help you either.

    Hewlett-Packard should have recalled products out there instead of selling a product that they can stand is no longer behind. It seems that the less these companies can make products, less likely to stand behind the products they make they are. Why go back to VIsta my only alternative? In my opinion, that I was hung up to dry.

    Hello

    HP does not support the dv2K, the 6K or 9K notebook series for windows 7.

    Most of the time, you need to use the Vista drivers from the support page and the model of the laptop driver that work very well.

    I have a portable dv6810us with W7 64 bit installed with the same video, so I don't know the vista driver works fine with W7.

    There are no updated drivers.

    Also, if you put a lot of pressure on your video card by playing games, your laptop will soon toast.

    They have defective mothers who as soon as the GPU overheating, the video cards, among other things, as the wireless, died.  Do a search on dv6000 motherboard issues.

    Right now, I recommend that use you your laptop to check e-mail and browse the web. I would not even listen to videos with her.

    If you are still determined to update the driver, then I recommend you to read this guide below and to focus on the section Option 2 for the card nVidia GeForce GO 6150 7150 M, 7200 M, 7400 M or 7600 M:

  • 17.0 browser update does not not my navigation on MANY sites, I have developed

    leandesign.com navigation bar does not. Display in a different browser to see the appropriate page. What happens on MANY sites that were designed for the customers.

    A quick response would be great!

    It looks like a victim of the user agent sniffing Exchange that the Gecko part changed in the user agent to Gecko/17.0 instead of Gecko/20100101 with previous versions of Firefox.

    This change must be restored in a 17.0.1, version of Firefox so you will have to wait for it.

    Quote: We are planning a FF17.0.1 and 17.0.1esr of these changes, should be unblocked (not) Friday

    It works in the current Aurora building that already has this change (for some reason any nightly does not have it).

    Found a workaround in this bug report by creating a special dispensation of pref (it seems to be a lot of them)

  • "communication not available with the printer" message when you try to print to a Lexmark 1270 x all-in-one

    I am running windows xp family.  I don't know what happened, but all of a sudden, I get this message when I try and print to my lexmark x 1270 "communication not available with the printer. I tried every troubleshooter, I contacted Lexmark support that they gave up, saying: it must be a file is missing from the windows registry, you can help me?

    It seems that if you say that the pilots were not reinstalled successfully.  What was the mystery file that could not be found?

    Do you remember how the software has been uninstalled?  Was something else than the control panel > Add / Remove Programs (or the link "Uninstall" from start > all programs) used?

    If you do not really clean things, attempts to reinstall the printer drivers may actually just end up putting the old drivers back in place.

    This is the easiest way to uninstall and reinstall the printer drivers: Article 1.  The critical step is #4.

    This page has more detailed advice for cleaning things out before you reinstall: http://members.shaw.ca/bsanders/CleanPrinterDrivers.htm

    I asked the firewall and antivirus applications because sometimes, some security software may interfere with the printers.  This shouldn't be a problem with the firewall of Windows XP and Microsoft Security Essentials.

    Finally, your problem could end up being hardware related.  Lexmark support has no hardware troubleshooting operation?  The manual for your x 1270 says:

    All-in-One is not communicating with the computer

    1. disconnect and reconnect both ends of the USB cable. For more help, see the
    installation documentation.
    2 unplug the power cord from the wall outlet, plug it in again, and
    Press Power. For more information, refer to the installation documentation.
    3 restart the computer. If the problem continues, remove and then reinstall
    the software. For more information, see page 16. [which ask you to remove the software using the link "Uninstall" - which is not complete, as described above]

    If you have another type of printer USB cable, you should try it exchanges.  Ideally, you need to connect to the printer on another computer, but maybe it's not convenient for you.

  • Availability of the critical apparatus report shows too many bars, not enough host names

    Hello

    The availability of critical devices report includes a graph showing the availability of each server in the selected period.

    On my report, I get 2 bars for each displayed hostname. Maybe the host names are not displayed as there a lot and the report is rendered for optimal playback.

    Even when export to HTML and looking at the source, host names are not available to extract and there is no option to export CSV. This is why I'm a bit stuck on how to generate a report with all the listed host names and their availability without going into the backend database.

    Any ideas?
