One needs to edit the course.conf file (assuming that you have admin privileges) to indicate the "consumer secret" for the LTI connection between webwork and the given LMS for grade passback.
The curious symbol of A-hat ("\hat A" in LaTeX) will appear just before the copyright symbol right after saving this file. And if there is more than one attempt to save this file additional A-hat symbols will precede the initial A-hat symbol. The disconcerting effect is that when trying to view or edit the course.conf webwork will return a message in pink text stating that
"This does not appear to be a text file".
Offered Solutions that have worked for us at HSU:
1.) Delete all the A-hat symbols that precede the copyright symbol then save you file and though a single A-hat symbol will still jump in next to the copywrite symbol, webwork will still recognize this as a text file and one can proceed.
2.) Delete the copyright symbol, but still keep the word "Copyright" in place in the course.conf file. And then subsequent saves for this file will still have a working file.
Given that the course.conf file can potentially lockout all users from a course if it has a glitch in it shouldn't this be addressed?
Or is there a simpler method that we have not seen here?
