Stuck on the debug page with error 500

[Jack202020]

I've activated the debug option in my back office to check something, when i've pressed save the debug page popup but now i'm stuck here, i can't login back to the back office, front end works just fine.

I didn't update or messed nothing up before activate the debug in the back office. What is the problem now? Can someone help me out? thanks!

Delete folder var/cache/dev If still an issue disable debug mode in config/defines.inc.php
