I transfer my wiki to Cloudflare service (with https).
Sometimes my wiki is showing mobile view where desktop view is expected.
Example:
http://lmgtfy.com/?q=Klawdija+%C5%81uzganowa+wiki.czarnobyl.pl http://lmgtfy.com/?q=Walery+Pierewaczenko+wiki.czarnobyl.pl
Looks good to me. Maybe cloudflare is caching the response, so if a mobile user first open a page, it caches the mobile view, and then a desktop user gets the cached mobile view instead.
Are u sure? I checked on three different computers and still the same. Main article and discusion page.
Yesterday when I checked, yes, it was the desktop view. Now is the mobile.
You have access to the access logs, so check them if requests are getting into your server, or served directly by cloudflare (and sending a wrongly cached response).
