Yes, it is a very clear and helpful message. Let's see what you are are told:
See the Configure WAF page, Block template=foo site template switch.
Let's go to the
documentation page of the Configure WAF page and search for "Block template=foo site template switch". Oh, there it is:
Another Joomla! hidden feature is the ability to switch between installed templates by passing a special URL parameter. For instance, if you want to apply the JA Purity template, just pass the parameter ?template=ja_purity. For a live example, have fun with http://www.joomla.org/?template=ja_purity. Enabling this option will turn off this hidden Joomla! feature.
What should we learn from that information? Joomla! allows you to switch the template used by the site when you pass it a template=something URL parameter. What does this Admin Tools' feature do? It blocks the use of that switch. Therefore, what can this possibly mean as a block reason? That someone tried to use such a template switching URL parameter and Admin Tools blocked them. Is there something not obvious? I'm asking this question honestly, without any trace of spite, as I'm too close to the code and documentation (I wrote both) to be their impartial judge. The only people who can provide feedback are my users, that means you. After all I'm writing the documentation for you, not me.
Please bear in mind that I am trying to reconcile the needs of two different and contradictory groups of users: on one hand I have those people who complain that the documentation is too big and on the other hand I have those who complain it's not detailed enough. I try to go for the middle ground. Any suggestions on performing this impossible task are always more than welcome.
