I'm not sure when this started, but I just noticed that some of my custom page templates do not reflect the changes I make anymore. I have no idea when or why this started happening. For example, if I comment out the header include in myCustomTemplate.php, a page using that template still shows my header. How does this happen?
If I rename the template to something else (and not file name but the actual template name in the php file) and make a change, then a page reflects it.
Page.php does not seem to have this problem either, but I've noticed at least two others do.
Can someone explain what is going on?
