 * Hello,
 * I’m asking for your help because I have a critical error on my website.
    I installed
   the W3 Total Cache plugin this afternoon. I followed the configuration help. 
   And when I pressed ok to validate the caches. The site went to error 500. So 
   I had no access to the site or to the wp admin interface.
 * So I went to Filezilla to delete the w3 Total cache plugin thinking that was 
   the only problem.
 * Except that now I have access to my site, but I don’t have access to the admin
   interface at all.
    When I want to access it an error message appears: “There 
   has been a critical error on this website. Learn more about troubleshooting WordPress.”
 * Can you please help me? How can I re-enable access to the interface?
 * Thanks
    Have a nice day.
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Finterface-wp-admin-inaccessible-wp-admin-interface-not-available%2F%3Foutput_format%3Dmd&locale=en_US)

 * Hello [@sicanucleaire13](https://wordpress.org/support/users/sicanucleaire13/)
 * Thank you for reaching out and I am happy to assist you with this.
    I’ve checked
   the login URL: [https://www.sicanucleaire.fr/wp-login.php](https://www.sicanucleaire.fr/wp-login.php)
   Can you please confirm if the issue occurs once you enter your credentials? Please
   remove the W3TC completely and re-install it. Delete wp-content files and folders–
   cache folder – w3tc-config folder – object-cache.php (if exists) – advanced-cache.
   php (if exists) – db.php (if exists) – upgrade folder – delete w3-total-cache
   folder in wp-content/plugins/ (if exists) Re-install W3 Total Cache Before re-
   installing, check if you have any other caching solution or any custom rules 
   in your .htaccess that may be causing the conflict. Once re-installed, enable
   the settings one by one and make sure to save all settings and purge the cache.
 * Thanks!
