I have read the post www.joomlapolis.com/component/option,com_joomlaboard/Itemid,/func,view/catid,78/id,99685/#99685
and followed the instructions there.

I got no SH404sef at all.
I have disabled all Joomla Plugins and also CB ones.
I have cleaned cache and disabled Joomla-Sef.
The behavior remains. No modules are shown in Lists and in MyProfile pages. Modules are shown in Mailbox.
I have no possibility to install a fresh copy, I got not database remaining on my provider. I will have to backup, delete, install fresh, delete and the restore. That will take at least a date.
Any ideas before to start such a procedure?

Update:

Modules are shown in other position except on the right position. On left position is shown also but it moves on the top right, not on the place it should be shown.

any ideas guys?
