I developed a site six months ago and now need to update it, but I can’t access the login page to get in to it.
I get a the following error page:
This is somewhat embarrassing…
I tried wp-login.php at end of URL as well but this also didn’t work.

Try disabling all your plugins by moving or deleting them from your /wp-content/plugins/ folder. Do this by FTP or by your host’s control panel.
If this doesn’t work, log in to the server via FTP, and upload a fresh copy of WordPress. This will fix your wp-admin, and any other folders or files that have been corrupted.
You can download a fresh copy of WordPress from WordPress.org.
For other solutions, including new login files and database-altering, see the WordPress Codex page on Login Issues.
They suggest that, in case all else fails, you post at the WordPress Support Forum. Be sure to give details of your server setup, if you know it, including mySQL and PHP versions, as well as your operating system (OS), browser, and the WordPress version that is causing these problems.
