XOOPS Version: 2.2.3 Final
PHP Version: 4.3.9
MySQL Version: 4.1.10
Web Server Software: Apache
Default Theme: default

Have deactivated all modules (not system). I have PHP Debug on.

When I try to access the ..../modules/profile/register.php, I get a blank/white/empty page, in my error log I get:

"PHP Fatal error: Call to a member function on a non-object in /home/uda/web/xoops/class/theme.php on line 499, referer: http://www.mysite.com/"
This is in the return statement of the getCachedTemplateId() function.

Generally, I get a lot of blank/white/empty pages after installing 2.2.3 Final. They seem to appear at random occasions. I have seen it after I have done various administrative changes - e.g. changeing the order of blocks, chaning char-set for a module, modifying my theme.html file, etc. "Normally" I have been able to get rid of them, by cleaning up my /templates_c/ dir, and sometimes by clearing browser history. But this one simply wont go away.

I have tried to go by the FAQ entry for this type of problems, but to no luck.

Are somebody please able to give me some help on this one?

Installed the "extended profiles" - and now I can see the page using the default theme. When using the theme of my choice, however, it does not display anything. I'm trying to use the kubrick theme compiled by kavaXtreme. (I should perhaps try to file a post under the theme forum on this one...)
