Even with exclusive well-written code, issues can arise. Here are solutions to frequent problems:

| Problem | Likely Cause | Solution | |--------|--------------|----------| | "Cannot connect to database" | Wrong DB credentials in config | Check db.php against phpMyAdmin settings. | | Blank page after login | PHP error reporting off | Enable error_reporting(E_ALL); at the top of index.php. | | Voter can vote multiple times | Session not destroyed properly | Verify has_voted field is updated and checked. | | Admin dashboard not showing charts | Missing GD library in PHP | Uncomment extension=gd in php.ini and restart server. | | GitHub clone permission denied | SSH key not set | Use https:// URL instead of git@. |
