We just migrated from a cPanel server to another (Server crash) and restored all functionality. There is however one problem with Horde/Turba, and I have no clue how to get that fixed.
When reading an email in Horde, and clicking on an email address link to add to to the Addressbook, it gives the error "Invalid address book".
Using Turba itself everything is working however.
I've got a customer with a problem where their emails are being sent multiple times for the last couple of days. They use horde religiously and will not use anything else. I believe they click the send button with double or triple clicks or until it sends.. This apparently was never an issue before.. I have managed to make it happen doing but only sending two emails at a time..
