I'm currently running Plesk Onyx Version 17.0.17 Update #12 on CentOS Linux 7.3.1611.
One of my customers has reported to me today that they're unable to install WordPress or any other applications that require a database through the Softaculous interface.
The error received is:
The MySQL Connection could not be established.
We are currently running version 4.8.6 of Softaculous and everything was fine until the latest update.
The MySQL server is up and running, I've also restarted the service and then restarted the whole server with no luck. I am able to create databases through the Plesk panel and am also able to create them manually on the command line.
This is a problem isolated to Softaculous and I'd appreciate any help.
