 * Hello everyone.
    I have recently installed the siteguard plugin and after activating
   it I am no longer able to access the site through the link mysite.it/wp-admin.
   From the control panel, ftp I went to wp-content, I found my plugin “siteguard”
   and renamed it, but I did not solve the problem. So I decided to delete it, but
   I still have access problems. Finally I renamed the whole plugins folder, but
   I still can not log in. thanks for the support
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fproblems-access-after-installing-a-plugin%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_

 * 404 indicates failure to communicate with the server. Reasons for this failure
   to communicate with the server can vary.
 * Try resetting your custom permalinks back to the default setting and renaming
   your WordPress .htaccess file. If that works, then try reading [Using_Permalinks ](http://codex.wordpress.org/Using_Permalinks)
   before setting a custom permalink structure again.
