I haven't been able to solve the puzzle - if there's any, however there is some interesting pattern in filenames.

/staticfiles/svg/error.33ab1eb5.svg -> 33ab1eb5 hexadecimal is 866852533, which seems to be a prime number.

I believe the probability is very low if unintended. Also other file names, can be factored more or less to 1 big prime number and few small primes.
