Troubleshooting Guide: Additional things to say

[wxtim]

Did your script fail because you needed to chmod?

Good idea.

log/config/flow-processed.cylc shows you the effect of Jinja2 templating.

Good idea, we could do with a general Jinja2 debugging section including cylc view -p and flow-processed.cylc.

log/config/01-start-01.cylc shows you the effect of Jinja2 and task parameter expansions.

I'm not sure we expand task params, or maybe just in runtime? Can't remember. Good to raise awareness of the config log directory, explain the file numbers and names and why they are useful.
