The instructions you provided is how I originally imported the installation. When I knew something was nto quite right was when I tried to fully back it up. I get a similar error
The following errors were found :
Could not connect to database, please check the
Username/Password of your database. If changed, please update the
details in Softaculous installations using Edit Details.
the username and password has been checked they are correct. You have any idea what is blocking interworx from being able to read the mysql DB?
