RSS Feeds not working or switching between each other
When I load mysite.com/es/feed/ it is sometimes is empty or shows the xml file for mysite.com/en/feed.
So English RSS feed is switching with Spanish RSS feed and viceversa happens as well.
I tested them with feedvalidator.org andhttps://validator.w3.org/feed/ and I get this error:
“This feed is valid, but interoperability with the widest range of feed readers could be improved by implementing the following recommendations.
Self reference doesn’t match document location”
<atom:link href=”https://www.mysite.com/es/feed/” rel=”self” type=”application/rss+xml” />
These are the cache headers for the mysite.com/en/feed/:
“Cache-control: must-revalidate, max-age=0, s-maxage=10
X-Cache: MISS from www.mysite.com
Transfer-Encoding: chunked
Content-Type: application/rss+xml; charset=UTF-8”
Please help. This only happens with polylang. I have tested disabling all other plugins and updating wordpress and polylang.
