@profc backup and make sure you delete all the BP Template Pack files transferred to your theme folder in server https://codex.buddypress.org/themes/theme-compatibility-1-7/bp-17-upgrading-template-packed-themes/

@profc
Has all of the buddypress files that the template pack plugin copied over in your theme been removed? If I remember correctly you would have to manually remove those via cpanel or FTP. I don’t think deactivating the plugin will remove them but its been awhile since I used it. Since 1.7+ I haven’t looked back! 🙂

@profc
You do not need to use BP Template Pack plugin with BuddyPress anymore! Please review:

Theme Compatibility & Template Files

That is probably why you are having this issue!

Hi, sorry so late for getting back to you. My ISP has been strange today. I just updated github Repo to 2.1 to allow up to 10 unblocked public pages. As before read the readme.txt and follow the commented instructions in private-community-for-bp.php

@profc
Use this plugin. Download the zip file and upload to your plugins directory. Read the readme.txt and make the adjustments in the commented code in private-community-for-bp.php before activating the plugin.

@profc first thing is upgrade to BP 1.7.1. Change to BP Default and see if issue is resolved – no black frame. Check if your preferred theme has been upgraded for BP 1.7+. Do also double-check that the plugins you’re using have been upgraded to latest BP version as well.
