I am no longer able to import items into Omeka (ver. 2.7); the import process begins as usual and then shows the status as Stopped, with no items added and none skipped.
There’s an Undo Import link, but that doesn’t work, so test imports are piling up.
When I turn on error logging, I see:
[CsvImport][#5] Stopped import or undo import due to error: Call to a member function getControllerName() on null
How do I fix this (and why did it start in the first place)?
