You can see many topics about issues in profile module in this forum.
Also it use too much resources (CPU + RAM)
As I and many others said in the past:
Profile module needs a complete rewrite.
It has the highest priority after the core content module.
It means core team should not do anything and should not commit any code to SVN before rewriting profile module.
IMO we should
encourage module developers to work as a team on some orphaned modules.
Currently many xoops developers works individually on some personal projects/modules and many of them has the least priority for xoops community.
IMO some developers just want to gain some credits by creating new low features, low performance modules instead of debuging old full feature ones.
If we can work together as a team we can have some strong modules match with community needs.
There are many examples of orphaned modules like profile, publisher, xhelp, ...
Trabis did a fantastic job for debuging some of them. unfortunately it seems Trabis leave xoops forever so we need more developers like Trabis.
Edit:
Deka87:
editor DHTML is hardcoded in profile.
please try this.
change in profile/class/field.php line 123:
$element = new XoopsFormDhtmlTextArea($caption, $name, $value, 10, 30);
with this:
$element = new XoopsFormEditor($caption, $name, $value, 10, 30);
The above is just a 2 second start. maybe you should define $name = "tinymce"
