I left work and the site was working as it should, when i got home, my theme i have wont display, basically I am left with no blocks around menus, and the color scheme of the theme is gone, so, all i have is a white background with links around, the am running XOOPS 2.0 and the errors i am getting are Notice: Undefined index: meta_desc in file /include/functions.php line 53
Notice: Object of class XoopsUser could not be converted to int in file /include/xoops13_header.php line 31 I made no changes, so, I dont know what has happened, please help

also, i have tried changing the theme, and i get no change, also i have missing blocks, and they are visible, on all layers, i can see them try to load, and them disapear... please, any suggestions?

First try by deleting all files in the template_c folder / directory except the index file.

Thank you Svaha, that worked, I appreciate the suggestion!
