I keep coming across the unknown exception error message when trying to edit or add to a vector layer. Anyone else come across this problem? Any fixes? I'm currently running QGIS 3.4

    Can you please edit your question and add some details about the data you are trying to edit. Thanks! – user2856 Aug 2 at 11:19

Export and save the layer which you want to edit in a different name of course. Now try to edit.

  • Same problem occurs even with the new layer. – Sam Letts Aug 2 at 12:19
