Hello,
I have tried to delete the widget, add a new one, move it and in each case I was unable to do anything because the error message with the JSON warning appeared.
I have deactivated and reactivated the Weaver show post and the Weaver Xtreme Theme support extensions without success. I get the same error message.
I might try other tests next week. Not in a hurry, but it’s concerning as I had no issues until recently.
Thanks for the help!
