Debug liquid tags in Octopress / Jekyll

Question

Any ideas how to see where liquid tags actually fail?

To be clearer, I'm having some trouble with a plugin and all I see on previewing my site is

Liquid Error: can’t convert Array into String

On my site. How do I get more debug information? Thanks

Answer 1

Try to run rake generate with --trace for more detailed information.

rake generate --trace

Commonly, it will give exactly where the error is promoted.Then simply print some variables or use debugger to debug.
