So basically my webpage is trying to connect to the database, but when I try to open the webpage, the error is printed and my database stops working.
Warning: PDOStatement::execute(): MySQL server has gone away
And this is printed in MySQL Workbench
FROM KORNELPC.err:
00:18:29 UTC - mysqld got exception 0xc0000005 ;
This could be because you hit a bug. It is also possible that this binary
or one of the libraries it was linked against is corrupt, improperly built,
or misconfigured. This error can also be caused by malfunctioning hardware.
Attempting to collect some information that could help diagnose the problem.
As this is a crash and something is definitely wrong, the information
collection process might fail.
key_buffer_size=8388608
read_buffer_size=65536
max_used_connections=4
max_threads=151
thread_count=4
connection_count=4
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 58341 K bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

Attempting backtrace. You can use the following information to find out
where mysqld died. If you see no messages after this, something went
terribly wrong...

The project I'm working on is just cloned from here https://github.com/StretchProjects/stretch-league, so you can look at this code. I'm new in PHP so I can't really debug this and track down this errors.
