Hi kaptelnaha23,
I’m sorry you had a bad experience with LearnPress. Our developers resolved this issue. Please delete Learnpress plugin on your site and install it again.
You can disable plugins by disable the plugin’s files or via Database.
* Disable the Files:
1. Login to your site’s files using the file manager provided by your web hosting company or using an FTP program such as Filezilla.
2 .Browse to the /wp-content/plugins/ folder.
3. Find the folder of the plugin you wish to disable.
4. Rename or delete that folder.
* Disable all plugins via the Database
1. You’ll need to access the database for your WordPress site, look for the wp_options table.
2. You’re looking for a row with the option called “active_plugins”.
3. On the next screen, you will need to change the “option_value” field to a:0:{} and then click on Go button to save your changes.
You can refer following article to know how to do it. http://www.wpbeginner.com/plugins/how-to-deactivate-all-plugins-when-not-able-to-access-wp-admin/
