For article 298, you have to replace // with #
Code:
# redirects any URL that includes: record_company.php/password_forgotten.php
RedirectMatch Permanent ^/(.*[record_company.php]+)/(password_forgotten.php)$ /page_not_found.php
# redirects any URL that includes: /images/wp- with 'wp-' being anything that ends with '.php'
# this allows for images named such as 'wp-header.jpg' to work
RedirectMatch Permanent ^/(.*[images]+)/(wp-.*\.php)$ /page_not_found.php
The code uses the wrong character to indicate a comment in the .htaccess file.
Dont know what the problem is the with other, since there are many modifications in there. More details please.
