Nevermind, giverphy, I managed to downgrade it. Thanks anyway for the tip itself!
It is working again on 2.14.18
@giverphy Can you offer me guidance on how you conducted the downgrade? Did you download the files of the previous release and replaced them via FTP or the backend file browser?
Or was it possible to do this more thoroughly somehow? Thanks in advance,
Timo
Thanks for the tip, @giverphy and thanks for the feedback, @123host. We are currently evaluating whether we downgrade or wait for the fix.
PS: Condolences for the campaign, @giverphy.
