Hello,

Please don't post so many topics and tickets regarding the same issue.

I have already replied you:

You can simply disable the error reporting in the "Global Configuration": screenpresso.com/=tu60f
Or you can disable it in the php.ini file on your localhost. Make sure there is display_errors = Off.
Have you tried this?
We have tested the demo copy on localhost and it worked without issue. Since you are working on localhost we are not able to help you, please move your website on a live server and check if the issue occurs.
