Hey there, looks like it could be an easy problem to fix.
Look at: Unknown column 't.intro' in 'field list'
So t.intro is missing. Great. Where is that?
Look at: t.intro FROM mdl_nanogong t
So the table is nanogong, which we'll refer to as "t".
So, create the column in nanogong, called intro! It's missing!
This is a custom plugin you've made, or some one has made, I assume.
