Background Information

Microsoft® deprecated the FrontPage® extensions for Linux in 2006. Since this time, the FrontPage® extensions have received no security support.

cPanel & WHM continued to install Microsoft FrontPage extensions by default until February, 2014. At that time, FrontPage was removed from EasyApache. In August, 2014 with the 11.44 release, cPanel provided tools for removing the FrontPage® extensions and announced that FrontPage would no longer be supported in future releases.

The 11.46 release is the first where all FrontPage functionality has been removed. To ensure that this change does not interrupt service for end users, upgrades to 11.46 are blocked when the FrontPage extensions are still installed. They must be removed before an update to 11.46 is allowed.



Customers that do not remove Microsoft FrontPage extensions from their servers will continue to run the 11.44 release of cPanel & WHM. All major releases of cPanel & WHM recieve one year of security support once the next major release is issued. Customers that do not remove the FrontPage® extensions during this timeframe will cease to recieve updates to their server.

The usage of FrontPage extensions is limited. Microsoft ended client support in April 2014 with FrontPage 2003.

This section should contain information on how this issue/topic can affect the customer.  Be specific! It should be broken up into easy to read sections and have subheadings (heading 4).


How to determine if your server is affected

You can determine if the FrontPage extensions are installed on cPanel & WHM version 11.44 and earlier by running the following command:

if [ -e /usr/local/frontpage/version5.0/bin/owsadm.exe ] ; then echo "Frontpage installed"; else echo "Frontpage not installed"; fi


You can get a list of the specific cPanel accounts on your server that have used the FrontPage extensions in the past by running the following command:

find /home/ -wholename '*/_vti_cnf/*' -type f | grep -E -v 'htaccess|virtfs' | cut -d '/' -f 3 | sort | uniq

If you have different, or multiple /home partitions you will want to replace /home/ noted in the above command with any different or additional home partitions


This section should contain information on how the customer can determine whether or not their servers are affected. If there is a script available, please attach it through the 'attachment' button at the bottom of the page.

Do not commit to specific product changes unless you have confirmation from the development team that is working on the change.

If you are providing specific commands to run, the code block macro is very helpful for distinguishing the text.  It also provides easier copy/pasting for the customer.  It is found under the '+insert' button and then choosing 'other macros.' You can also use keyboard shortcuts by typing { and then start typing the word code. 


If your system has no users that appear to be using the FrontPage extensions, you can remove them by running the below command via command line as root:

/scripts/unsetupfp4 --all


If there are users on the system that have used the FrontPage® extensions recently, cPanel recommends you contact them and migrate to WebDAV instead.

For Microsoft FrontPage, this can be done by the recommend article:



If users are unwilling or unable to migrate off the FrontPage extensions, cPanel recommends transferring the account to a system locked to the 11.44 LTS release.

With cPanel & WHM 11.44 and earlier, FrontPage functionality will break whenever EasyApache is recompiled. If you wish to maintain this functionality, you should perform the following steps on the command line as the root user: 

  1. Download and unzip the custom module into the /var/cpanel/easy/apache/custom_opt_mods/ directory.
  2. On the command line, run the following commands:

tar -C /var/cpanel/easy/apache/custom_opt_mods -xzf custom_opt_mod-frontpage-20140912.tar.gz

3. Run EasyApache via WHM >> EasyApache

Automatic unused FrontPage installation removal in build

To help our customers stay on the most up-to-date version of cPanel & WHM, version introduces an automatic removal system that automatically removes unused Microsoft FrontPage installations. This system should resolve blocker issues for most cPanel & WHM servers that this blocker affected.

We released this build on January 12, 2015.
