I've had my WordPress site up and running successfully for about three months, the URL is http://www.comicsninja.com. It was fine last night but suddenly this morning the formatting is all messed up and I can not get into the Admin dashboard. The error message says:
Warning: sem_get() [function.sem-get]: failed for key 0x152b: Permission denied in /home1/comicsni/public_html/wp-content/plugins/wp-cache/wp-cache-phase2.php on line 98
Warning: Cannot modify header information - headers already sent by (output started at /home1/comicsni/public_html/wp-content/plugins/wp-cache/wp-cache-phase2.php:98) in /home1/comicsni/public_html/wp-includes/pluggable.php on line 868
Any idea what is going on and how I can get back into my Admin page? Thanks.
