I updated to the latest version of WP-United and somewhere I seem to have managed to break the installation of the mod for PHPBB. As a consequence I get very long loading times and according to my webhost "broken packages" are sent, which causes the server to lock my IP out from accessing my site. Quite bad, in other words. And it seems related.
I have tried purging the various caches, disabling plugins and settings in every way thinkable and even gone through the modifications for the PhpBB files without any improvement. It seems as if the theme and user integration is what is causing the problems, as when I turn those off, then the rest of the site, including the forum is working again.
Even in Admin, the Chrome loading symbol seems to run for a very long time after having saved any WP-United setting.
Furthermore, I can't access the PHPBB Admin via the menu, only through writing the URL directly.
I also have W3 Total Cache installed. Does this come in conflict?
Any advise on what I should try?
