Hi, when running the phpList Updater it jumps immediately to the last step “Perform update” and returns an error message:
Updater is loading
Cannot set the maintenance mode on!
This happens when trying to update from v3.6.6 to v3.6.7. It also happened in all earlier versions and I tried to investigate the problem a couple of times, unsuccessfully. The used accound is a super administrator.
I attached a screenshot of the message.
Do you have any ideas, suggestions…? Thanks in advance!!
