 * I tried to activate the plugin math-quiz and it generates a problem but answering
   it never works. The problem is now that I cannot login anymore on my admin page,
 * I always get this error:
 * Invalid problem. Please go back and try another one.
 * But I cannot even disable it because I cannot log in as an admin.
 * Is there a special way to temporary disable it by adding some suffix to the URL
   or any another way to fix it ?
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fcannot-login-as-admin-invalid-problem%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_

 * Sorry for the late response.
 * To manually disable it, just delete the plugin folder located under /wp-content/
   plugins/.
