Twice today I encountered a problem that the Polylang language switcher on the homepage was no longer working. Where I normally land on the Dutch version of the page I was now redirected to the English version and clicking the Dutch flag on top kept on redirecting me to the English version.
The only way I could fix this was by purging the cache but a few hours later the same happened again.
The problem only seemed to occur on desktop. I could reach the Dutch page on my mobile.
As this seemed to be something related to caching and now happened for the first time after I have installed W3 Total Cache yesterday I think it must be related to this plugin.
I have the default settings for page cache.
This is what’s enabled:
– Cache posts page
– Cache SSL
– Don’t cache logged in users
I could just stop caching the front page but as I don’t quite understand what’s going on this functionality could just start appearing on other posts and pages…
