Bit of a strange one.
I have put a script in the miscellaneous scripts section in
Configuration->General->Design, but it is not showing when I look at the page source. I have tried putting
<script>code here</script> and just plain text, such as 12345, but when I refresh the website, it does not show in the page source.
I have refreshed caches through Magento admin etc. but it still just does not update. Tried logging out and back in, same thing. The text I enter shows in the database, so it is getting saved back, but just not showing on frontend.
