    Recently after the move I've had a problem with this forum that occurs only every now and then.
    When I click to open a thread, the page is sometimes completely blank. However, when I view the source code, it seems to all be there. When I reload the page it works fine.

    Running Firefox and I was wondering if anyone else had the same problem.

    I am seeing same thing in firefox, that the code is 100% there really seems odd. I worked on it today, and got email working fully. Just.....still having random blank pages, refresh fixes it, adn as you said looking at source it is all there

    Can't say I've noticed such a problem, and I visit the forums 6 -10 times per day. Browser is Opera 9.21 on Windows XP SP2.

    I just had the same thing posting a new message, another blank page.
    Hit the back button and reposted, and the message was only posted once..

    And again, this time on the main forum page.. I used "View generated source" on the Web Developer toolbar :)love:) and it just displayed this:

    <html><head></head><body><p><a href="rssposter.php"></a></p></body></html>
    So it would seem that some JavaScript is actually getting rid of the HTML rather than it being a rendering error.

    I haven't ever installed or managed vBulletin, but I'm beginning to think it depends on AJAX to execute certain scheduled tasks in order for the page to load quickly and still not need any external scheduler.
    It might be the scheduled updating of the RSS feed that makes Firefox return the blank page.

    The reason I suspect the scheduled task is because:
    • The link to rssposter.php in the resulting HTML
    • Some JavaScript is replacing the HTML source with aforementioned link
    • The page normally does not contain any JavaScript that would do this particular replacement

    Hmm, seems it's in fact using a script producing a transparent 1x1 GIF image for scheduled tasks.. so much for that theory :)

    Another blank page, and it did contain a scheduled task. I'm not sure how this thing that's supposed to be an image would throw off Firefox though.
    Unfortunately I forgot to turn on my packet sniffer before visiting the forum :)

    I will check into this when I get a moment, it is certainly odd. i checked it for an hour or two one day and even found a few other reports of it on some vB forums.
