Will Custom filters with with a $table_prefix other than wp_ ?
New to WordPress, I setup a wordpress site with my host and tested the plugin had custom filters working.
During this test phase the recent wordpress hacking attempt happened, so I read some of the suggested setup options to improve security.
When I setup the actual site for my client I changed the wordpress $table_prefix setting. Plugin works but custom filters do not. Thought it may be security/permission issue with their host, but as a test I setup another site on my host with a custom $table_prefix, plugin works but custom filters do not.
