My site agnewsolutions.co.uk has been running perfectly until I installed Sidebar Login and now the website returned a 500 Internal Server Error.
I spoke to the host and they said that the .htaccess had changed so they fixed it, now the front-end of the site is accessible but I cannot login with my details - I do have the correct username and password and I do have cookies enabled in my browser as I can log into all my other WordPress sites which are setup in exactly the same way.
When attempting to log in it provides the following error message:
ERROR: Cookies are blocked or not supported by your browser. You must enable cookies to use WordPress.
This is clearly a problem with the site due to recent changes, I believe it is due to this recent plugin but I cannot log in to make any changes.
If you could take a look at my site (agnewsolutions.co.uk) the login page is (http://www.agnewsolutions.co.uk/wp-login.php?hide_my_wp=agnewsolutions) and provide a solutions that would be very much appreciated!
Thanks,
