wp-admin url not found

Hi,

I would really appreciate your help. I just installed this plugin and hours later the wp-admin url is not found. I logged in to my dashboard through wp-login but I would like to know where my wp-admin is placed and how I can modify it to have access to it.

I deactivate the plugin but it does not solve the problem, my wp-admin is still not found.

I would really appreciate your help as this problem make conflicts with other plugins such as my plugin of cache stop working because it does not have the proper link of the wp-admin.
