I was trying to use ctrl+shift+/ to comment out code and was getting the wrong comment delimiters, the PHP ones in fact.
After messing around with config files, disabling all packages, etc., I noticed that the bottom right syntax identifier in the status bar says PHP when in an HTML File.
If I click on it to change the syntax, it shows as HTML being selected. If I change the syntax to XML for example then back to HTML, it still shows PHP in the status bar.
Any way to fix this? So far as I can tell its not any of my plugins.
