my problem is as following:
yesterday I updated to Version 2.2 from 2.1.3. Everything went well, no probs so far.
Then I installed the plugin "Simple Tagging" to replace my "UTW". Again everything went well, I was able to import the tags and implement it in the theme.
Then I edited the tags, deleted some, and created new ones in the "manage tags" section. After that the whole CSS-Design went nuts, it fell completely apart, but curiously only in Firefox. The site showed no problems in IE6.
I tried everything to repair it again: deactivated the plugin, deleted the implementation in the theme, even activated the normal WP-Theme, nothing.
This is weird, I thought the blog-appearence is solely controlled by the activated theme?
Only a restore of a backup of all files made it work again.
Now I have 2.1.3 again, and this time when I try to update to 2.2, I get the error immediately.
My theme is a heavely redisigned "cutline"-Theme.
Is it possible that the msql-datebase got broke somehow? But then again a broken database can not create css-problems. Why does a change of the theme have no effect?
I have no idea whats causing the error.
Thank you for some hints.
