Hey Mike,
I've not solved the unexpected token yet, something on the server setting but haven't got a clue what. I'm going to convince client to move hosting I think. Would like to know the solution.
But regarding the error log problem, what Susan is referring to is on this page:
http://rtfm.modx.com/display/ADDON/MIGX
See Step 2: Set up the MIGX Configurator Custom Manager Page (CMP) and Package Manager
I normally always get this issue and have to run the MIGX configuration.
That should solve that error of the missing table but didn't fix unexpected token.
