This error can occur during or after an upgrade process.

Cause:
In the source table of the page there is a field with a wrong tablerelation, in that case with value “Table 0”. That can occur, if the selected table in the table relation was moved, removed or renamed, especially, if that table is a custom table or a table part of a module.

Solution:
Edit the source table of that page, check all fields with tablerelations. Replace value “Table 0” with the correct value.
