We have just activated cloudflare on our website. Only when CF is activated and running we get a critical wordpress error when our server sided script tries to create a PDF brochure. (try to print a property brochure on www.gruposoltura.com)
Cause the script uses images from the server we have created a firewall rule allowing traffic from its own server IP. Still this does not solve the problem.
Does anyone have an idea how to solve this?
