Coding: hooks.php Parse, syntax error

My webhost engineers have advised that the issue appears to be my .htaccess file – it has additional rewrite rules in it, possibly from another WP plugin, that are incorrect

They have commented them out so only the default WP rules are in the file.

The logs currently show the following:

PHP Parse error: syntax error, unexpected $end in /mnt/website/standard/l/i/lisasweddingworld.com/web/wp-content/themes/omega/lib/hooks.php on line 405

Can someone please help? I cannot log in to my site at all?
