 * Hi!
 * Try manually deactivating your plugin (no Dashboard access required) using one
   of the two methods listed below (also described [here](https://wordpress.org/support/article/faq-troubleshooting/#how-to-deactivate-all-plugins-when-not-able-to-access-the-administrative-menus)).
 * 1. Deactivate your plugin via [FTP](https://wordpress.org/support/article/ftp-clients/)
   or the file manager provided in your host’s control panel.
    - Navigate to the `wp-contents/plugins` folder
    - Rename the folder `ultimate-member` in it to `ultimate-member.hold`
    - Go to Dashboard > Plugins and you’ll see the “missing” plugin ( ultimate-member)
      has been disabled.
 * 2. Use [phpMyAdmin](https://wordpress.org/support/article/phpmyadmin/) to deactivate
   all plugins.
    - In the table _wp\_options_, under the _option\_name_ column find the `active_plugins`
      field. (The table prefix of _wp\__ may be different if you changed it when
      installing)
    - On this row, change the `option_value` field to: `a:0:{}`. **Save the changes
      and this will deactivate all plugins.**
    - Then from Dashboard > Plugins you need to reactivate all plugins, except the
      one causing you troubles – ultimate-member
 * After you regain access to your Dashboard,
    I recommend asking at [https://wordpress.org/support/plugin/ultimate-member](https://wordpress.org/support/plugin/ultimate-member)
   so the plugin’s developers and support community can help you with this.
 * Hope this helps,
    Kind regards!
