Sorry, I did not know as I am new to this product and new to this forum. I was acting on an email from another tech who just said "upload the file to our research forum, they can work on this". They also gave the link "https://support.malwarebytes.com/docs/DOC-1087" which did not say anything about a log file. It was just instructions to join the forum, zip the file and post it. The instruction about making the log file do not seem to apply for our version. The first step shows "Type in "mbam.exe /developer", without the quotes". The file mbam.exe does not seem to be on the computer. I looked with both file explorer and the command dir c:\mbam.exe /s" in a command window.
