Give me more details. Did you use “Admin menu access” add-on to block those menu items? If yes, what is going wrong?
Does user still can open the linked URL?
Can you provide access to plugin or theme which registered those menu items/URLs?
Yes, I blocked everything, I left only a creation and editing of posts.
However, this item still appears in the Author menu.
He is also on the White List, as you can see in the image: https://ibb.co/mmEpdd
OK. I need to make my own tests with it. What about access to the plugin or theme which registered those menu items?
If it’s not critical for your data, you can export your site (without wp-uploads) using UpdraftPlus plugin and share files with support [at-sign] role-editor.com via DropBox or Google Drive.
