Membership plugin is blocking access to Simple:Press forum

I’ve been using the Membership Lite plugin for about a year now, and it works perfectly. However, recently I set up a Simple:stuck_out_tongue:ress forum on the same site, and the membership plugin isn’t allowing access to it.

I’ve added the forum’s home page to it, and that works fine. However, going into the actual forums takes me to my access denied page *most* of the time. Sometimes it works fine. I’ve also added shortcodes programatically and given my membership levels permissions for those without any luck. I also tried adding the forum pages to a URL group, but then the rest of my site is not accessible.

Anyway, I’d appreciate any suggestions. Thanks.
