Thanks for the explanation. When i press shift and save it still fails for me.
I will either remove the commands from the table or discuss this with my Web host.
Do you know if i disable mod_security will this cause me security problems or is it safe to disable?
i found the night mode plugin settings and changed the background color from black to something else and it now shows it fine.
thanks i already contacted App developers and they said they couldn’t work out why it fails. I am speaking to my web host now and it looks like an issue with some settings there.
