Here's the problem. It used to work fine. What happened?
http://countrygarden.ceconn.com

I'm using 3.6.4

I've tried adding lines to htaccess but that just gave me 500 internal error.

Also, my host does not have Suhosin. What do I do and why doesn't it work now when it worked before?

When you say 'it worked before' what do you mean? What have you done since it use to work?

Try disabling all our plugins, it could be a memory issue, but it sure looks like the suhosin issue.

Tell your host that the theme uses stream wrappers and the php is throwing an error when the first one is being used. the 'stream wrapper' for 'bfa://' needs to be allowed.

I mean before it stopped working.

Anyway, I sent your message to my host. Hopefully, they'll be able to fix whatever needs fixing.

Did you change anything?
Add a new plugin, add a new post?

Nothing. Not a thing. My host migrated me to another server. Does that mean anything? However, my other sites are working.

My host migrated me to another server

this absolutely means something. The new server is most likely configured different from the old server and this new configuration is the root of the problem. I would get after them to solve this since they caused it.
