This is a new problem for us. I was running 3.15.something and we started getting the error (was running fine at some point). I just updated to 3.17.4+190529 and the error is persisting.
Any help how to resolve this problem is appreciated, thank you!
You need to adapt the modsecurity configuration (e.g. remove rules or deactivate rules for certain paths or URLS). You will need to check the mod security log files to see what rule is triggered.
To let everyone know, I use HostGator for my hosting. Apparently, they changed something and I don't have access to that log file. A chat with tech support and clearing my cache resolved the issue. The technician said they whitelisted the path that was causing the problem, but didn't give me specifics.
