Fix: 500 Internal Server Error & Storage Permissions

A blank white screen or HTTP 500 Internal Server Error typically indicates web server permission restrictions or missing environment keys. Follow these steps:

# 1. Enable Debug Mode in .env to inspect exact exception trace:
APP_DEBUG=true
APP_ENV=local
# 2. Grant write permissions to web server (Nginx / Apache www-data):
sudo chown -R www-data:www-data /var/www/html/
sudo chmod -R 755 /var/www/html/
sudo chmod -R 777 uploads/ cache/
💡 Pro-Tip for cPanel: If you are running on cPanel shared hosting, ensure directory permissions are set to 755 and files to 644. Permissions of 777 on cPanel will trigger an automatic 500 error due to suPHP security checks.

Fix: MySQL "Got a packet bigger than max_allowed_packet" (Error 1153)

When importing the SQL database for Naxos v1.8.0 – App Landing Page Template Free, large tables or sample demonstration data may exceed the default 16MB/64MB MySQL packet limit, producing Error 1153.

# Solution A: Import via command line with increased packet size:
mysql --max_allowed_packet=256M -u db_user -p db_name < database.sql
# Solution B: Edit /etc/mysql/my.cnf and add under [mysqld]:
max_allowed_packet = 256M
sql_mode = ""
# Restart MySQL daemon:
sudo systemctl restart mysql

SQL Mode Notice: If you receive only_full_group_by syntax errors, setting 'strict' => false in config/database.php or clearing sql_mode resolves this instantly.

Fix: cURL Error 60 "SSL certificate problem: unable to get local issuer certificate"

This error occurs during payment gateway callbacks (PayPal, Stripe) or license verification webhooks because the PHP environment lacks an updated Mozilla CA certificate authority bundle.

# 1. Download official Mozilla CA bundle:
curl -o /etc/ssl/certs/cacert.pem https://curl.se/ca/cacert.pem
# 2. Add to your php.ini:
curl.cainfo = "/etc/ssl/certs/cacert.pem"
openssl.cafile = "/etc/ssl/certs/cacert.pem"
# 3. Restart PHP-FPM:
sudo systemctl restart php7.4-fpm
