Intriguing – I had not noticed that till you said.

I am still getting similar time to first bite as before – both Safari and Firefox are up to date and the link is not constrained in any way.

AJAX is (amongst lots of other bits) designed to allow you to update bits of a web page without reloading it all (think of a web shopping cart where you can update the quantity) or call functionality that lives outside of WordPress core but still use WP functions. Details can be found at https://developer.wordpress.org/plugins/javascript/ajax/

The drawback is that these tools / code are not cached normally so they can hit the server CPU / disk heavily if they are used a lot on a page.

IIRC this type code is server side only and cause 502 and 504 errors to be displayed if they are in trouble – not something I can remember seeing here for a long time (if ever – cannot remember either way TBH). It should not impact anything on your machine and pressing the button (whoops) does not clear my browser cache.

The odd thing is I cannot see why I as a lowly user should have access to this as a menu item 🙂 I have not use s2Member Pro on a WP Site so unsure how it runs – possibly this is a quirk with me having an old WP admin account for other sites with the same email as I use here???

I do remember (but it is fading fast I am happy to say) AJAX is a bit of a pain and can break if some directory security is set up so we may have to live with it for now if Mike needs it for testing some things 🙁
