Tutorial [Fix] Xtream UI : 500 Internal Server Error

[Winter]

Cause:
Most 500 errors come from PHP-FPM hitting its memory limit during script execution.

Check current limit:

grep memory_limit /home/xtreamcodes/iptv_xtream_codes/php/lib/php.ini<br>

Edit config:

sudo nano /home/xtreamcodes/iptv_xtream_codes/php/lib/php.ini<br>

Change this line:
memory_limit = 128M

Recommended values:

1GB RAM → 256M <br>2GB RAM → 512M <br>4GB RAM → 1024M <br>8GB+ RAM → 1536M<br>

Restart Xtream UI:

sudo systemctl restart xtreamui<br># or<br>sudo /home/xtreamcodes/iptv_xtream_codes/start_services.sh

After restart, your 500 error should be gone.
