Can't access WP dashboard after plugin activation

I installed and activated the WPMU Dev Dashboard plugin, logged in to my WPMU account in the WP dashboard, and then added the site to my account in the WPMU. When I went back to my dashboard in WP, I wasn't able to access any page. Every page just redirected to /wp-admin/admin.php?page=wpmudev.

I finally had to go to SFTP and manually remove the plugin in order to access anything in the dashboard of my site. It looks like I have access to the Pro Features for the Smush plugin (which is why we purchased a WPMU plan), but why did that happen and how can I prevent that from happening again? We plan on using your plugins on our client's accounts as well, and we need to be able to have this work correctly and as intended.

I'm unable to grant you access to the site because as I said, I had to completely delete the plugin from the site in order to get anywhere in my dashboard at all.

Thanks.

    Hi Rob

    I hope you had a wonderful day.

    This is weird and isn't supposed to happen. I have all my sites added but I didn't face this issue in my WordPress sites. I just tried to regenerate this again on my live test sites, but I still could not regenerate.

    Would you mind allowing Support Access so we can have a closer look at this?

    To enable support access you can follow this guide here:
    https://premium.wpmudev.org/manuals/wpmu-dev-dashboard-enabling-staff-login/

    Moreover, can you turn on the debug mode in WordPress and then activate the plugin again? To enable it, open your wp-config.php file and look for define(‘WP_DEBUG’, false);. Change it to:

    define('WP_DEBUG', true);

    In order to enable the error logging to a file on the server you need to add yet one more similar line:

    define( 'WP_DEBUG_LOG', true );

    In this case the errors will be saved to a debug.log log file inside the /wp-content/directory.

    Depending on whether you want your errors to be only logged or also displayed on the screen you should also have this line there, immediately after the line mentioned above:

    define( 'WP_DEBUG_DISPLAY', false );

    The wp-config.php is located in your WordPress root directory. It’s the same file where the database configuration settings are. You will have to access it by FTP or SFTP in order to edit it.

    Past errors here. If file is very long, please paste them to a text file and attach with your reply.

    Have a nice day. Cheers!
