I have update my Joomla from V3.4 to V3.5 and below error is showing.

"NetworkError: 404 Component not found. - http://example.com/administrator/index.php?option=com_ajax&group=system&plugin=sendStats&format=raw"

I tried to place die('here'); in administrator/components/com_ajax/ajax.php and there is no output.

  • In the Joomla backend, go to Extensions >> Manage >> Manage, then see if Ajax Interface is in the list of installed extensions

It seems like the Ajax Interface has somehow been lost in the Joomla update, however the files are still there.

I've heard of this happening before and believe it's a Joomla bug.

Seeing as the files are still there, go to your Joomla back-end, then go to:

Extensions >> Manage >> Discover

You should see the Ajax Interface component appear, which you can then install.
