General server settings / maintenance message
If one edits general server settings via web interface and in the "Message to display" there is following:
Something something .
Something else something else.
Second line for some reason is doubled into Settings.php and results into 500 error.
Of course that is because of ; at the end of the line that is doubled. Dunno if that is because of the empty line in between . But this will happen every time even one doesn't edit this field at all.
First noticed this when edited forum title and big bada boom error 500. Then I made a test and it wasn't just a glitch in the matrix ...
Thanks and have a good one!
