Hi,
Thanks for your reply.
Yes it is activated, no filters, no changes. I left it as it was after activating. I have enable debug mode. Still the same. I have even uninstalled app and reinstalled it, no changes. I tried using the test url at the bottom and it says it found a similar post. Tried opening the link again after the test, still says error 404.
The problem only started since after the update.
