Hi, i changed the collation of the tables to utf8mb4_unicode_ci 

after that i was abled to update the timeline but then i got php error on every page.

i restored a backup from before the update to be able to get the site back online.

what i notice is that when i make a change in the settings or when i update a module i have to flush the dynamic cache for the update or setting to be shown in the studio.

also when i now try the update again i het an error that to many files were modified.

even when i force the update ignoring modified files.
