I started a "check" on a database and this task does nothing and apears every time I log on.
The database itself is in order (a second check went through). What can I do?
your previous task didn't seem to finish correctly, so that Plesk didn't delete the ( temporary ) task. Pls. consider to use the "Plesk repair utility", with the example command ( logged in as user "root" over SSH ) :
plesk repair db -y -v
Pls. consider to read as well the Plesk documentation, in order to inform yourself about additional options and descriptions:
