Hi,
I have just migrated a site to a new server, and upgraded it to 2.2.1. Everything seemed to be working fine. I then installed MSM and when setting up Site B, chose to duplicate the Site A templates and all but one channel.
Now I am finding that the CP is really slow 90% of the time, to the point where the edit screens seem to fail to load fully, and display a broken layout.
I also have some PHP errors in Membership Preferences > Channel Assignment. The only channel I did not duplicate (the important one!) has its channel id rather than name displayed in the channel list, and above it are these errors:
A PHP Error was encountered
Severity: Notice
Message: Undefined index: options
Filename: members/edit_member_group.php
Line Number: 136A PHP Error was encountered
Severity: Notice
Message: Undefined index: options
Filename: members/edit_member_group.php
Line Number: 137
Other relevant info:
Latest versions of EE and MSM (downloaded yesterday)
Our server is already running plenty of other EE sites
No extensions enabled
Freeform and AJW data import modules installed
Caches cleared
No errors reported during upgrade/installation
Public site seems fine
