Hello,

I updated our site and now it has error messages, the problem is that I'm not sure if I did it or not. I've googled the error message with little success, and searched the forums with the message or part of the message, but struggled to work out the error.

I work in IT, but I'm a bit of a dimwit when as regards HTML error messages and our webmaster does not have web access at home at the mo. I'd like to try and fix this but need a little help. If you look at our site you'll soon see what the error is.

Any ideas or pointers in the right direction gratefully recieved.

Cheers

This is the first (and most important error message):

fopen(/home/capitalc/public_html/tmp/cache/contentcache.php) failed to open stream: Permission denied

Check your permissions in tmp/cache they should be 777

Thanks for your quick reply. I think that I do not have the correct rights to fix this as my login is basic and I cannot add pages or make changes to the site  just add text to them, and this error is do to with permissions. Might be wrong though, but thanks anyway
