MS Frontpage extension is no longer working after we switch to Litespeed Web server.
It was working before with Apache.
Users are unable to login to the Frontpage anymore.
The fix is to comment out <LocationMatch "^/_vti_bin/.*.exe> </LocationMatch> section in /etc/httpd/conf.d/mod_frontpage.conf
Later build of LSWS will do that automatically, no further actions is required.
