A customer running 9.8.9 has been experiencing the following failure from the 11th of July. They got upgraded to 9.8.8 in June and yesterday to 9.8.9 to see if this would resolve the problem. The login time when logging in to Admin is also quite long, and i think that this issue here could be the culprit.
Anyone who has experinced similar and knows what to do?
