I'm having this random issue:
In some pages (not always the same, and without a readable pattern), the pages are served as XML/feed and not as HTML.
What I've found out is that the correct
<meta http-equiv="content-type" content="text/html; charset=utf-8" />
is generated as
<meta http-equiv="content-type" content="application/rss+xml; charset=utf-8" />
I'm using an Apache 2.2.15 server, and PHP 5.3.17, Joomla 3.5.1, and my guess is that this is something related to the cache of Joomla (currently using progressive cache, file, 15 minutes), and also a cache control plugin CacheControl.
Does anyone have/had the same problem?
How do I solve this?
