Fatal Error

Hello

I keep getting a fatal error message on my website. I’m not sure what has happened as it was working yesterday and I did not add any updates.

‘Fatal error: Maximum execution time of 30 seconds exceeded in /homepages/11/d686643080/htdocs/app798770999/wp-includes/class.wp-dependencies.php on line 256’

I am also unable to log in – it states ‘Error: The password you entered for the username is incorrect’ and cannot recover the password. The login page also takes long to load.

Any help would be appreciated.
