Apologies for the late reply Tom, I was trying to sort out this issue (we fixed the caching on Cloudflare’s side, but the queries are still present in bulk when I’m forced to purge the cache). I couldn’t find the query using the query monitor plugin.
I spoke to my hosting about it, and they said:
“The queries are most likely not shown in the query monitor because they are somehow connected to the ‘admin-ajax.php’.
Unfortunately, we do not have the debug tools in order to identify the direct caller.”
We tried disabling other plugins but the queries were still present. Do you have any other ideas as to what this might be?
