After sorting the above, it all seemed ok.
However I am now getting the following when trying to login to Horde:
Oct 03 09:07:53 HORDE [notice] [horde] Login success for firstname.lastname@example.org
[x.x.x.x] to Horde [on line 90 of "/usr/share/horde/login.php"]
Oct 03 09:08:45 HORDE [error] [horde] Error retrieving session data (id = hs4s45qs11nbh95j9e3e71j504): Lock wait timeout exceeded; try restarting transaction [on line 110 of "/usr/share/horde/lib/Horde/SessionHandler/mysql.php"]
I have dropped and recreated the horde database, and still get the above error.
I need help please.
