One of my website 'domain.tld' returns 500 - Internal server error. All others sites works fine.

From domain logs, the following error appears:

    # tail -f /var/www/vhosts/
    /var/www/vhosts/my.domain.tld/httpdocs/.htaccess: RewriteRule: bad flag delimiters


From the error it is clear that the issue is with the file /var/www/vhosts/domain.tld/httpdocs/.htaccess.

.htaccess files provide a way to make configuration changes on a per-directory basis. A file, containing one or more configuration directives, is placed in a particular document directory, and the directives apply to that directory, and all subdirectories thereof.


Rename the .htaccess file to /var/www/vhosts/domain.tld/httpdocs/.htaccess_backup and check the access to website and domain logs once again.
