Elk 1.1.2, php 7.2.3
When deleting a board with existing posts, this error occurs:
A warning could certainly be in order. Better yet perhaps a prompt to move existing threads to another board? ;)
You should read "Selected board still has posts and/or topics." instead. :P
Oops. Seems I did, though the memory isn't always the best either. :D
Funnily enough, the code seems correct, so I have to test it and see what is wrong.
I did a test right now and looks good...are you sure you have the file Errors.english.php? (Just to exclude this possibility.)
