### Apache will not start when attempt to include LTI

We are running version WeBWorK-2.13 and pg_version PG-2.13. It appears to run okay, but when we try to start the LTI facility the apache webserver code will not start. I get the error below. Only thing that I did was remove the # comment on the line 'include("conf/authen_LTI.conf");' in the localOverrides.conf file. The authen_LTI.conf file seems set up okay.

Weird part is that in trying to figure out the problem I replace the above line with 'include("conf/'authen.conf");' where the authen.conf file only had one line in it of "#test". Starting apache with this include gave the identical error that the original include did. So it seems that the 'include' command is messing up.

Any ideas to help me?

Chances are there is a perl syntax error in the localOverrides.conf. The config files are read as perl files. Try perl localOverrides.conf and look for syntax errors. There may be some undefined variable warnings which would not be significant but it may spot mismatched parentheses or mismatched quotes. In reply to Michael Gage ### Re: Apache will not start when attempt to include LTI by Randal Dalhoff - I had already tried that and this is the result: [wwadmin@webworktest conf]$ perl localOverrides.conf
Undefined subroutine &main::include called at localOverrides.conf line 397.

I even tried replacing the 'include' with 'require' which passed the perl run test, but found an error in the authen_LTI.conf file. I had put a $in the$LTIBasicConsumerSecret variable which was causing the problem. Forgot to escape it.

All is well now.
