I am running a LAMP-stack Wordpress application (usage/limit is memory 161MB/1GB, disk: 323MB/5GB), and I frequently see ‘buffer overflow detected’ messages popping up when I run my server.

This had been happening sporadically over the last few days, and as of today it happens every single time I restart apache2.

I’m the only person loading the site but every time it’s loaded the buffer overflow error presents itself. I’ve restarted the workspace, I’ve uninstalled and reinstalled apache2 after updating apt-get yet the error remains. At this point I don’t know how to debug or resolve, and would greatly appreciate it if someone could help me out.
What’s odd is I can access phpmyadmin with no issue, I can even go to /wp-admin with no issue; however, when I try to load the site itself, it throws this error.
