Update...got the apache error to go away but still had the edit issue. Then remembered that I have a localized version of the system.template where the only two changes are where the "WeBWorK" name in the banner is something local and the maa.org logo and link directed to our campus logo and link. With these changes, the editor issue still comes up. When I switch back to math4 with the standard name and link and logo, the editor works as expected. Odd.
