Template Error: The template file must be given (or the template could not be opened)
I got alerted to the above error by nagios (http check) on a cPanel server.
Luckily it’s simple to fix.
Login to WHM as root (important), and then search for ‘web template manager’ in the search box. Click on it to open.
Then you just need to click on ‘revert to default’ and this should fix your issue (it fixed mine). :)
