Error: Deleting Sale Not Working, shows “Something Went Wrong Please Try again Later”

Issue:

Sometimes, when attempting to delete a sale, the system may display the following error:

“Something went wrong. Please try again later.”

This usually occurs due to a database configuration issue.

Solution:

Follow the steps below to diagnose and fix the issue:

Step 1: Check the Error Log:

Navigate to your application’s log file located at: pos/storage/logs/laravel.log

Step 2: Identify the Error:

If the log shows the following error: General error: Prepared statement needs to be re-prepared

Step 3: Update Database Configuration:

Open the database configuration file located at:

pos/config/database.php

Find the MySQL configuration block and ensure it includes the following option:

  • ‘mysql’ => [
  • ‘driver’ => ‘mysql’,
  • ‘url’ => env(‘DATABASE_URL’),
  • ‘host’ => env(‘DB_HOST’, ‘127.0.0.1’),
  • ‘port’ => env(‘DB_PORT’, ‘3306’),
  • ‘database’ => env(‘DB_DATABASE’, ‘forge’),
  • ‘username’ => env(‘DB_USERNAME’, ‘forge’),
  • ‘password’ => env(‘DB_PASSWORD’, ”),
  • ‘unix_socket’ => env(‘DB_SOCKET’, ”),
  • ‘charset’ => ‘utf8mb4’,
  • ‘collation’ => ‘utf8mb4_unicode_ci’,
  • ‘prefix’ => ”,
  • ‘prefix_indexes’ => true,
  • ‘strict’ => false,
  • ‘engine’ => null,
  • ‘options’ => extension_loaded(‘pdo_mysql’) ? array_filter([
  • PDO::MYSQL_ATTR_SSL_CA => env(‘MYSQL_ATTR_SSL_CA’),
  • \PDO::ATTR_EMULATE_PREPARES => true, // Add this line
  • ]) : [],
  • ],
  • Important: Make sure the line \PDO::ATTR_EMULATE_PREPARES => true is included under the options array. This setting helps prevent the “re-prepared” error by enabling emulation of prepared statements.

Step 4: Save Changes:

After updating the configuration save the file.
