After about 3 years of absence and very low webmaster activation i finally upgrade my main huge website jadoogaran.org (database size is about 1Gig) from 2.2 to 2.5.4
the xoops website information is:
xoops XOOPS 2.5.4
The upgrade process goes almost smooth and i could solve some minor issues but i have a really strange problem with the profile module.
firstly i should explain that jadoogaran.org has about 25 custom groups.
after upgrade I informed that some users have blank pages in userinfo.php
i should explain that i can not see any error when i activate the debug mode for all users (in xoops_data/configs/xoopsconfig.php 0 - To all users)
i investigate the issue really deep (it takes about 20 hours for me) and finally i found that users belong to one special group have this problem.
that special group id is 20.
IMHO the group id=20 has some conflict with group id=2 (registered users)
when i removed the user from one of the above groups (2 or 20) its problem had been solved.
please reproduce this issue from your end.
i should repeat that i can not see any error when i activate the debug mode for all users. (because i login with that user belong to groups is 2 and 20 and group id 2 and 20 have not any admin permission)
@Mamba and trabis:
i will send you a pm contain the user and password of an example user with blank page.
