last week i had a weird bug in this site , occasional 404 error was raised all over the site , sometimes the site was working fine but other times  i was getting 404 errors  as a result  theme files were not loaded and i even couldn’t login to dashboard nor cpnael  .

I went through and tried every thing like checking file permissions , deactivating all plugins , reviewing .htaccess file and even reinstalling wordpress files (which was 2.9.2+ by the way )   , but nothing helped at all and i began to suspect that the host is the cause , but lately i came across this thread in wordpress support  which wasn’t solved but indicated that wordpress version might be the cause…

i upgraded to wordpress 3.0.1 and i will keep checking the site from time to time , i hope that the upgrade has solved this bug ..i wonder if anyone else found the cause for this bug?
