Hi,
This is one of the problem that you don't know what is happening :
1) open a notebook and try %md ### this is a test
2) Run it and get the expected results
3) remove the interpreter using the interpreter settings page
4) try running the paragraph again and get an error : "md interpreter not
found"
Log file will show:
ERROR [2015-08-17 11:02:22,782] ({qtp2095490653-45}

5) Add the interpreter back using the interpreter setting page
6) try running the paragraph again
*still getting the same error both on page and in log*
7) open a new notebook and try using md
8) *everything works fine in the new notebook*
So for some reason, after removing an interpreter and getting an error it
can't be re-attached to the notebook.
BTW, even restarting the server did not sole the problem
