After migrating my site from one host to another, I started to receive a 403 error when trying to log into my site’s back-end. I hadn’t changed anything since the migration, and after doing some research, I found this: http://wordpress.org/support/topic/403-forbidden-error-page-1.
I removed the Brute Force code from my root .htaccess file, as the plugin author suggested, and I was able to access my log in screen. However, after entering the correct credentials, I keep receiving an Access denied. https://www.evernote.com/shard/s2/sh/2a52c8c5-2a30-41f6-b06a-40c2b5da7646/55e2593650af2633aceca1557be9f2b8 message.
I checked in with my hosting provider, and they confirmed that it wasn’t a permissions issue. Also, they even tried disabling the top 2 offending rules from mod_sec, to no avail.
Does anyone have suggestions on what could be causing this issue?
