Hi, all. I'm trying to get the latest version of WebPA running, and I'm
running into problems with the LTI connector. I've gone through the
installation instructions (running Composer, updating the database tables,
etc.), but I'm getting the following in my error log. (Please ignore the
ugly file paths...the work, but they're a legacy of the previous system,
and will possibly be getting cleaned up later.):

I'm afraid my PHP is rudimentary at best, so I'm not sure what might be
happening...can anyone give me an idea? Thanks in advance.
