We have a WP Multi site with some plugins and we're getting PHP injections all the time, generating queues of 5-10k every time. We already installed some security plugins (All In One WP Security) but nothing.
The server has Nginx and Varnish and also other WP sites that aren't facing any problem.
We want someone that fixes this on a detinitive way and tell us why is this happening.
We want experts, and this should be done in less than 1h.
