When I visit http: // servername / moodle / admin / settings.php ?section=editorsettingsatto and click the "Save Changes" button, I get this message: "This site can't be reached. The connection was reset. ERR_CONNECTION_RESET".
However, when I visithttp: // servername / moodle / admin / category.php?category=editoratto and click the "Save Changes" button, everything works just fine.
I have look at everything I can think of, including the server error logs and I can find nothing, save the message below. This problem only seems to occur, right now, when changing parameters on Site administration. When I do something else, say for example: Authentication, LDAP server, it works perfectly fine. It hasn't happened on the front end yet.
The only thing I did find when I enabled Apache debug was this when I tried to Save:
[Sun Sep 13 18:17:04.965814 2020] [charset_lite:debug] [pid 31885] mod_charset_lite.c(219): [client: ipaddr] AH01448: incomplete configuration: src unspecified, dst unspecified, referer: http:// servername . domain. com/ moodle/ admin/ settings.php?section=atto_equation_settings. The config.php file has this in it for wwwroot = 'http: // servername /moodle'
Anyone have any ideas about what might be causing this?
