Hi Abdullah,
I checked both the debug output and the log.txt. The its the log.txt accessed via the plugin’s page (where it says to view / clear debug log) that doesn’t seem to be getting populated despite the proper debug flags. The file is 0 bytes.
I tried this again just now. De-activated from the plugin side. Went to the Google permissions to remove the 3rd party access for GSheetConnector. Then went back to the plugin to Get Code and re-authorize.
I’m still not seeing anything in the log.txt file and still not getting the form contents posted to the sheet. The form is simple with 5 fields, all fields are lowercase, one word, and i didn’t have issues with this previously.
