I attached 2 pages:
1) normal_view.txt - source code of "control panel" page. Code is strange, but view is ok
2) com_templates.txt - source code of "Template manager" page. Screenshot of it in my previous post.
Thanks for answer and I hope it's not a big problem for you.
Well, i think it must be something related to some 3rd party extension you have installed, because i'm not seeing that problem (see screenshot). One thing, i did notice a problem the first time i tried, but the error message was related to sh404sef. I uninstalled sh404sef, and the problem went away. Perhaps you have that installed????
