We are sorry... page not found

[smalltowndev]

Hi there, I just did a fresh install and finished the setup. I was working for a few minutes when, suddenly, no pages can be found. I see a call for a shutdown function in the following directory: adm_program/system/bootstrap/

I attached a screenshot. Do you have any suggestions on what's causing this? I set file permissions for adm_my_files to 777 and the sql user is working I can see the tables.
