@PitaJ Yes i wrote in 2 post first of this.
I installed version 1.1.0 but when im logged , the site was again freezed.
For this i deleted dump.rdb from redis folder and i redid "./nodebb setup" to re-create the database.
After i tried to re-create the bug, for this i uploaded the same "Image/Logo" and change "Site Title" . But no problems.
Now seems work all perfecly.
There is a urgent bug in 1.1.2 . I think that there is a bug in the database.
I noticed that at the beginning , before of the bug in 1.1.2 , the cover of profile didn't worked, the users upload the image , but was invisible "all white". Worked only the avatar.
In 1.1.0 this bug there isn't and at the beginning , the cover of profile worked.
There is something broken in 1.1.2 .....
