Questions

thanks for doing that, User, errors are not likely to be fixed unless we know about them!
please signal errors from your Board, if you can. to report the error please describe it in detail and tell us the web address where it occurs (copy from the browser window). sending a screenshot is also a good idea.

example of a well reported error:
I am trying to upload a Tricky.eml file by drag and drop in the Media section of my Wordpress site admin zone on:
https://mywpsite.com/wp-admin/media-new.php
but I am getting an error:
>>>
“Tricky.eml” has failed to upload.
Sorry, this file type is not permitted for security reasons.
