Took fire as result of poor editing! (7)
I believe the answer is:
ignited
'took fire' is the definition.
('ignite' can be a synonym of 'take fire')
'poor editing' is the wordplay.
'poor' is an anagram indicator.
'editing' with letters rearranged gives 'IGNITED'.
'as result of' acts as a link.
(Other definitions for ignited that I've seen before include "Set on fire" , "Lit" , "Set alight" , "Kindled" , "Gin diet (anag.)" .)
