Until you bumped this old topic I had no idea you could do LaTex in the new dbCode. Awesome! I learned LaTex two years ago so I could do calculus homework that looked like I was a real mathematician.
Yeah I think it's a bit more in-depth, and gives some better examples. I mostly use it to look up the various non-obvious math codes.
The problem appears to be that the PHP file_get_contents routine cannot include a backslash in the file string, so I can't fetch a copy to store locally.
Why do you need a backslash to get at a local file? Is it a Windows filesystem?
