Let deal with the search issue first rather trying to address multiple items at once. I think that’ll be easier for us … definitely easier for me and faster.
First question, do you have any security related plugins installed, such as WP-SpamShield?
If you do, check their option for anything about blocking suspicious queries.
I’m focussing on this directory because something is cause a 403 access denied message on query strings that are outside the root domain.
For example, this core WordPress search will work on you site:
http://www.pilgrimassembliesinternational.org/?s=churches
But if I go up a page:
http://www.pilgrimassembliesinternational.org/churches/?s=chuches
This will fail. NOTE, this is the core WP search, see the ?s
a Connections search will be ?cn-s
.
This should show the WordPress search results page. Instead, the server response with a 403 access denied message.
This can be caused by a plugin or a server setting… So let start by looking at plugins.
