The plugin can hide the plugin settings pages per WP Role and per WP User which can prevent you from accessing it and (e.g.) authorize the plugin. You can set those permissions via the 'Permissions' tab on the main plugin settings page:
So this fix this issue, please make sure that your account is selected for the different permissions. If you can't access the settings page with your current account, use an Admin account that has permission to access the settings page. When the plugin is installed, all Admin account will have permission to access the settings page.
If you somehow don't have an admin account with the right permission, you will need to manually change the code of the plugin to allow all Administrator user to access the page. To do so, just follow these instructions:
- Open wp-content/plugins/{use-your-drive/out-of-the-box/share-one-drive/lets-box}/includes/Helpers.php
- Search for
if (current_user_can('setup_network')) { - Uncomment this block and save the file
After this change, the menu will become available again for all Administrators. This modification will be lost when you update the plugin in the future, so please add your account for the different permissions directly after you have made this change.
