Hi,
I think this error generally means the .htaccess stuff is not working:
openemr/.htaccess at master · openemr/openemr · GitHub
Which is usually either because:
- Apache has been set to ignore .htaccess
- Or you are using Alias in apache which then need to incorporate this instead into the apache site config like so: openemr/openemr.conf at master · openemr/openemr · GitHub
