I am experiencing an issue where my Raspberry Pi 3 is no longer able to boot. The image runs apache, WordPress, NextCloud, and an email server. Everything was working fine for around a month and a half and then today I received a Jetpack report saying the WordPress site was down. Going to the website resulted in a blank page - however, NextCloud and the email server still worked without any problems. Logging in via SSH gave the message *** stack smashing detected ***, so I restarted the pi. However, on booting I now receive the following error message:
Tried the sd card on a Raspberry Pi 2 and receive the same output. Unfortunately the text scrolls too fast to read what precedes it and it looks like it is not possible to scroll back up via the keyboard - the power light on it doesn't even turn on anymore.
