BulletProof Security Forum

Hi

I am running a site at mpsc.uk.com with BPS Pro installed. When a user is logged in and attempts to post a reply to a post on there this generates a page with a 403 error alert in a large rectangular box.

I have attempted to troubleshoot and have taken the following steps as advised by you previously on a different matter:

1. On the Security Modes page, click the Root Folder BulletProof Mode Deactivate button. See Custom Code Note if doing this step works.
2. On the Security Modes page, click the wp-admin Folder BulletProof Mode Deactivate button.  See Custom Code Note if doing this step works.
3. On the Security Modes page, click the Plugin Firewall BulletProof Mode Deactivate button.

In this state the Mingle Forum posts work fine. The site is currently in this state.

The following security log entries were generated:
