We've got a WordPress site integrated with a PHP script that generates web pages. The PHP script is administered via a subdirectory which has .htaccess password protection. This was all working fine but at some point apparently WordPress did something to make the admin subdirectory inaccessible! One of the lines that WP put into the .htaccess file in the root directory is RewriteRule . /index.php [L] and if I comment it out then the admin is accessible (but this breaks some of the links in WP). Also, if I remove the subdirectory .htaccess then the admin page comes up but obviously that is not an acceptable solution ;-) I also tried adding RewriteEngine Off as the first line in the subdir .htaccess but it didn't help either.
Any ideas please?
