I got this error box all of a sudden:
"Performance Warning
The cache directory is not writable - this will adversely affect the performance of your forum."
I did nothing to the code today and neither did any of my other staff. What is this and how do I fix i?
Check the permissions of your cache directory, it should be 755.
You can even empty the cache directory, it could solve your problem
Admin - Maintenance - Forum maintenance - Routine and then the last option.
The cache is 777.
Is that bad?
no, should be fine. If your host don't mind :)
It's possible that your host just turned on security tools such as suPHP, which blocks access to "world writable" directories and files. Is there some reason you use 777 permissions? Just for fun, try 755 and see if the problem goes away. Then try 775. Also read my sig > FAQs article on Proper Permissions.
