WordPress Login Receiving 404 Message (Host said it was because of the theme)

Hello,

When I go to my login page (http://www.jdaenglish.com/wp-admin), it redirects to an 404 not found page.

I contacted my hosting company about this and they say it’s because of the theme. Here is what the operator said in full:

This is happening in light of recent updates to WordPress and many theme compatiblity issues that arise because with the changes to how WordPress handles functions.php and the redirect from /wp-admin to /wp-login.php, some themes are triggering mod_security that block the site. You would need to contact your theme developer for assistance in resolving this in light of the new WordPress updates; however, it should reset in about 20 minutes to 1 hour time and you should then be able to log in, without the 404 error

I disabled my plugins and I’m still getting the error. Could you look into this for me?

Thanks in advance for your response.

Jack.

P.S. I’ll update this thread if I can log in within the next hour or two.
