Just as a piece of information, in case those looking into it haven't seen this yet and if it helps to track down the issue:
The problem seems to only occur when you are logged into OS2World. If you log out then the thread becomes visible (but of course you can't post to it).
I don't know how ID specific it is but just because my ID can't see the thread doesn't mean anyone else will have a problem. Whatever it is though is on a specific page, once that page is "Full" and a new one is created then that page can be seen (the problematic page is, at least usually, still a problem). Recently, for instance, Remy was unable to view the ffmpegca thread but I could. After adding a new post to it the thread increased to a new page and he could then view the new page.

Hi Andy,
The problem is with the Joomla wrapper. The way to avoid this is as Thomas indicates below:
Currently, we are at a loss in solving this issue. In the meantime, the best thing to do is to go to the link above, log in there, then use the forums. Seems logging in via Joomla may reset a normal forum login and log you out... so one should log into either (a) the forums only, or (b) Joomla first, then the forums via the link above.
This bug affects ALL page related functions of the forum (for instance, logging in via the Joomla wrapper may cause (1) threads being entirely inaccessible, (2) parts of threads being inaccessible (ie: Page 3-5 of a 8 page thread), (3) Private Message list pages (all or some of them) being inaccessible, etc). The end result is a page with the OS/2 World website header, followed by... nothing... on the affected forum sections.
This issues has been discussed with numerous others in the CMS field, including, if memory serves, people who use and/or work on the Joomla wrapper. Sadly, to no avail (yet).
Best,
Robert
