Add Fast 500 Error Tracker + Fix awk error in analyzer
NEW SCRIPT: modules/website/500-error-tracker.sh - FAST-ONLY 500 error detection (no menus, no options) - Scans access logs for 500 errors - Maps domains to cPanel usernames - Automatically diagnoses root causes by checking error_log files - Shows actual PHP errors causing the 500s ROOT CAUSE DETECTION: - PHP Memory Exhausted (shows current limit) - PHP Fatal Errors - PHP Syntax Errors - Missing PHP Functions/Extensions - Database Connection Failures - .htaccess Issues - Shows ACTUAL error examples, not just suggestions FIXES: - Fixed awk error in website-error-analyzer.sh: • Changed "next" in END block to "if (length > 0)" • "next" cannot be used in END block in awk - Added option 2 in Website Management menu - Renumbered all WordPress tools (3-16) DIFFERENCE FROM FULL ANALYZER: Full Analyzer: All errors, filters, time ranges, user choices Fast Tracker: ONLY 500s, auto-diagnosis, shows WHY not suggestions Use Fast Tracker when you need to quickly find which domains are getting 500 errors and the exact PHP errors causing them.
