This has just started recently. Once in a while, when i first go to our website it will open about 6 extra windows (example.com/wp-admin/admin-ajax.php?code=hjgtyiyuohyuh.......). Each page has simply a "0" on it.
Not sure what is causing this. I have been disabling plugins, but don't find the source of the problem yet. Any ideas what it could be?
Thanks
