I'm glad things are almost set up with your WeBWorK installation. I think I can help with a couple of your questions:
I have tried using eg "locate set7.def" but it doesn't show up anywhere.
set definitions are now stored internally in the WeBWorK database and
don't show up in files anywhere UNLESS you export them. To explicitly
export a set you choose "Export selected sets" in the "Hmwk Sets
Editor" -- you will be asked to define file names for the exported sets
-- usually I use names such as set7.def, but you don't have to. This
operation creates an ordinary text file (a "set definition file")of the
kind familiar to those who used webwork 1.9. You can "import" this set
definition file back into the WeBWorK database using the import
function on the "Hmwk sets editor" page. The export/import feature is
intended to allow you to transfer sets from one course to another, or
to backup or archive a course.
Some of the displayed formulas appear in a gigantic font.
Chances are you have a few equations which were created while you were
setting up the system -- and they were gigantic because you were still
adjusting the dvipng parameters.
You need to flush the cache that saves these equations. You can do this by running the script
..../webwork2/bin/remove_stale_images. There are directions at the top of the script or type
I'm not sure that I can help more with the last problem. It seems that
match in AliasMatch is not matching, hence $1 and $2 are not defined.
This has been reported before -- for example in
The solution there required recompiling mod_perl. You can use the
search function on this page with AliasMatch to get more help.
Hope this helps.
