Hi there,
My wiki is having an identical problem as the following bug report with respect to "Error creating thumbnail: File missing" --> https://phabricator.miraheze.org/T4130
I have not deleted any files and this issue has seemingly arisen in the last few days
Link to my wiki: https://thecsc.miraheze.org/wiki/The_Conn_Smythe_Corner
Example page with broken images (table columns contain images): https://thecsc.miraheze.org/wiki/Draft_Picks
Thank you for any help! :)
