Which is why you should consider making separate permission tokens for this plugin so people can grant you access to that section without granting access to other vital areas of the wordpress panel….

The permisson that grants access to the WP User Frontend section of the dashboard is the same permission that grants access to edit all the server and site options.

You must understand that I cannot give out the credentials to a user account that could turn my site upside down, even if I mark it private.

Maybe you should make your plugin run on separate permission tokens, so that people can grant access to the WP User Frontend’s section, but not the website options.

First, this is a slightly different issue as my errors are in the back-end (WP dashboard), while the ones in the video are on the front-end.

The post contents in the video is saved, but for me the form changes are not saved.

Also, I am not going to turn off PHP errors. PHP errors are not there to be ignored.

Posting the live URL would not help as the saving issue and the errors are in the back-end WordPress panel, and not visible on the front-end.
