I've just upgraded from newbb2 to cbb1.15, and immediately I've noticed some problems.

There is something wrong with displaying the date of posting. Instead of day and month (let's say 4/5) it shows: "YEurope/BerlinstEurope/Berlinrday". But not in all of the posts. I think that only in the newest ones (or maybe only in those I've entered in after upgrading?)
I've checked if my global time zone pref. or something got changed, but no, it looks (in main preferences page) that it's ok.
I've updated the System module, and it fixed another problem - wrong displaying of the home page's blocks.
But this strange text in date of posts is still there.

Could anyone explain it to me? And give some advices what can I do to fix it? I'd be thankful!
(Xoops version is 2.0.13.2)

I think the problem you are having is with the version of CBB you installed. I would check out the developement site to see which one is best for XOOPS 2.0.13.2. Here is a link to some good stuff. However, the CBB module 3.00 is RC. If you search aroung some more you should be able to find the version which will work better for your XOOPS version.

Module Packages for XOOPS 2.0, etc etc etc

Many Thanks to Phpb!

Thank you, Quest!
I didn't find this page by myself. Now I can make some more inquiry :)
(I still feel lost in all this world of support, development, and fan pages of Xoops... not to mention versions, updates, changes etc of modules. Too much of welfare ;))
