I find my Wordpress driven site rather slow and am trying to do whatever I can to increase its speed. I found a plugin called WP-Cache which should help with load times. However, after I have activated the plugin, I keep getting an error message:
Warning: sem_get() [function.sem-get]: failed for key 0x152b: Permission denied in /primus/users/u84/raoc/pub
e2.php on line 98
I've tried finding a solution to this online but no luck. I'm not entirely sure what the issue is. I've looked into the file permission settings and that shouldn't be the problem.
The only thing I can think of is that my site is running on a Zeus web server so there may be some incapability issues. Anyway, if anyone has any suggestions, I can really use the help. Thanks!
