Firstly, not to be impatient but to try and resolve things as I wait (support ticket posted) - I am seeing this error 'code: EX0' on many pages.

I know from past versions (not upgrades), yet a site I installed running 4.0.8 had issues and although I never managed to resolve it myself - it did seem very common. I have searched the error but what I have found hasn't helped me so far.

The activity stream for example presents the same error - Here.

Any ideas how I can fix it folks?

checked the logs? log into ACP> Support> Diagnostic Logs (in bottom right corner)  ;; this should help with Ex0, maybe give some insight.

 

Have you tried running the support tool? ACP>Support>Support>Something isn't working correctly.

I've ran the support tool, hasn't helped but thank you for suggesting it @MADMAN32395

Take look on error logs on ACP or in /uploads/logs.
