I dont know. But it eats up a ton of resources. Its coded wrong. I’ve talked about it here before, but the short answer is this…
I click like on an activity = 1 admin-ajax call (no problem)
I click like on another activity = 2 admin-ajax calls ( Hmmmmm )
I click like on another activity = 4 admin-ajax calls ( what?)
I click like on another activity = 8 admin-ajax calls ( whoa )
You can google admin-ajax to see how it taxes the server. Now imagine all your users scrolling through the activity feed and clicking multiple likes.
The attached screenshot is from your site after I clicked like 4 times
I think part of the upload problem is your server taking so long to process large images. It has to not only save the original, but make thumbnail, med and large version of the image as well. I have no problem uploading that image you gave me to my sites.
