I worked on my first extension today (based on the structure and files of youtube-miner).
As soon as I imported it into MineMeld I got the ERROR RETRIEVING EXTENSIONS LIST: INTERNAL SERVER ERROR red box of shame.
What log should I be looking in for clues? I've searched a bit and I know this was the path of the local folder. I removed it but that hasn't helped.
/opt/minemeld/local/library/3238b8cf-ecb2-4d32-b5e8-afa8d0f68b91/
I found this in minemeld-web.log,

Two additional learnings:
- The file being referred to here was minemeld.json (I had a dangling comma )
ValueError: Expecting property name: line 11 column 9 (char 425)
- I hadn't actually removed the library folder (though I thought I had). Once I deleted that (with the bad file), I was able to clear the error and reimport the Git project.
