I have disabled database via API. And now want to re-enable via ISPC panel. I tick "Active" option and while trying to save new settings receive error: "The database charset can not be changed". It is set to "DB-default" and I definitely not changing it. Is it possible to re-activate access via MySQL cli?
If it says that it gets changed, then it gets changed. Most likely you created the database with a charset not available in ISPConfig GUI or with now charset using the API, which will cause a change of charset when using the GUI. To fix that, manually set the right charset in web_database table for this database and then activate it.
Ha, the problem was that setting is case sensitive and I have used uppercase UTF8 via API. Damn. Solution: set utf8 .
