Problem Description
- During a backup you receive the error: Unable to back up application. Error: Failed to parse metadata
Problem Resolution
If you *are* using the Plesk application catalogue and/or Plesk Toolkit, then follow the steps in the Plesk knowledgebase here.
If you are not using the Plesk application catalogue and/or Plesk Toolkit (you use Installatron / 1-click web apps instead), follow these steps in Plesk:
- Tools & Settings > Database Servers > Small icon on far right of "Maria DB" line
- Select the apsc database
- Look for the aps_package table in the list and select "Empty" beside it.
- Uncheck "Enable Foreign Key Checks" option
- Click OK
This will clear the old entries in the app catalogue that we don't need.
