Problems with mod_security
Some hosts have an Apache module installed by default called mod_security. It blocks big POST requests, meaning it doesn’t let Mountee save bigger templates files. If you’ve experienced this problem, Mountee will have alerted you.
The Solution
You need to turn off the Security Filter engine by adding the following to your .htaccess file:
<IfModule mod_security.c>
SecFilterEngine Off
</IfModule>
Alternatively, you can use “SecFilterScanPOST Off“ if you don’t want to completely disable it.
