Not an issue. I just want to share that Cloudflare > Scrape Shield > Email Obfuscation (enabled by default in Cloudflare) will interfere with a Post Answer animation when the answer contains a mention (e.g. @awijasa). Note that BuddyPress is also installed in my case.
Cloudflare Email Obfuscation often set an email address to [email protected] even in an AJAX call.
I want to pass along a potential cause of this Email Obfuscation problem from a colleague who has tested CloudFlare Email Obfuscation extensively:
CloudFlare only obfuscates emails when the content being returned from the server has a MIME type of text/html or application/xhtml+xml. When an email address is being obfuscated in an AJAX call it is typically because the correct content-type is not being sent by the server.
Since this happened on an answer with a mention, this problem may have something to do with the BuddyPress plugin.
