When I try to open the User Control Panel or the section with private messages the following error occurs:
SQL ERROR [ mysqli ]
Got error 28 from storage engine [/code]
The same happens if I try to send a PM when I visit a user’s profile and click on “Send private message”.
Viewing my posts works.
Another problem with the forum software: I don’t receive email notifications when there are new posts in watched threads or when I receive new PMs.
Browser is Firefox 69.0.
