Resolving 5XX errors on the website

0001-01-01

I will perform a full audit and fix 5XX errors on the site:

• 500 Internal Server Error
• 502 Bad Gateway
• 503 Service Unavailable
• 504 Gateway Timeout

I will check configurations of Nginx/Apache, PHP-FPM, database and eliminate the root causes of the failures.
I will set up optimizations so these errors do not recur.
Result — a stable site without crashes or hidden issues.
