- Install and activate the User Role Editor plugin.
- Editor the Role Capabilities each role you wish to allow Media Library access. Add the `upload_files` capability to each role.
- Install and activate the Code Snippets plugin.
- Download this zip file: code-snippet.zip
- Unzip the downloaded file.
- Import the unzipped file into the Code Snippets plugin and then activate the imported Code Snippet.
After the above steps are followed, the Media Library button for the Bio and Notes fields will be accessible to logged in WP Users editing their linked Connections Entry.
