   Hi,

   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.

   I was able to fix the error by disabling the wp-cache plugin. Haven't tried to reenable it or anything to get it working again though.

   You know, I had a similar issue, but not with a plugin, but with customizing a Thesis theme.

   Check your wp-config.php file against a fresh default file (same file... wp-config-sample.php)

   I was missing the ?> at the end of the file.

   I am not sure why this occurred, but it did and when I read this, I thought I would toss that in there as it just happened to me yesterday.

   I just had the same problem and followed kddubb's advice by removing WP-Cache which I had installed about 10 minutes before which worked.

   Thanks so much was about to panic then!

   Any ideas whay this happens with WP -Cache though? & maybe an alternative plugin?

   Thanks

   Haven't tried it myself but thought this might help as a solution.
