When I make a change to “app/design/adminhtml/default/default/template/page/head.phtml” or other files in the adminhtml folders, the changes I make have no effect on the site. The site seems to be using old versions of my files but I have no idea where it is getting them from. I have deleted the cache multiple times and logged in/out of admin. I’ve also managed to turn on path hints in the admin panel and can see that the correct files are being used but the code in the files is incorrect. If I rename the file to _head.phtml then as you'd expect, the styling, js and meta tags etc go missing but when I make a simple edit to that same file the change is not reflected.
I recently upgraded from 1.6.2 to 1.7 - Am I missing something?
