Error:
softaculous: plugin disabled: Can not find /var/softaculous Installer may still be running, check install.log
Fix:
This fix is only for InterWorx, other control panels will probably vary.
Go into the var folder: cd var
Make the softaculous folder: mkdir softaculous
Set permissions: \chown -R iworx:iworx ./softaculous
Now update the scripts in Softaculous.
