json GET issue led to site shutdown - urgent
I am getting the following line which is causing a spike in my CPU usage. I have disabled and deleted the Discuz plugin, but still have this line coming up. Is there any way to deal with it... my host (Siteground) is going to shut down my site if I don't fix it today.

This issue comes from the Siteground cache system it has a hard cache, you should delete the caches and minified files.
You can also activate the wpDiscuz plugin and disable the live update feature.
Okay... I have deleted the Caches and minified files from Siteground as well as the SG Optimizer plugin.
I have disabled the live updates. The problem still remains.
Also, please note that we have previously done the above as well as we have deleted the plugin, but the wpdiscuz line still remains.

I can see this issue on several posts. All the time WPDiscuz support is shifting blame to your host yet the host is blaming the plugin for the spike in CPU usage.
Did you finally address the issue?
