What?
Why?
If
get_the_term_list()
returns for some reason aWP_Error
object for a given post (we noticed this as a result of a cache invalidation bug), the affected request will result in the following PHP fatal. While the problem is not really on the post terms block, I think it should handle such cases gracefully.How?
It checks the return value of
get_the_term_list()
to make sure we are always returning astring
on the block render callback.Testing Instructions
