Issue
After upgrading the CMS to 4.4.0 my layouts list is empty. But the selection bar below the list shows 5 groups of layouts. In the database I see 28 layouts of which 5 are retired. The text below the list states: “Showing 0 to 0 of 0 entries (filtered from NaN total entries)”. Klikking on “Clear Filters” doesn’t help.
