<h4>Migration Tool Fix</h4><ul><li><strong>function.php:</strong> Had <code>die;</code> on line 57 — debug code left by original developer that killed PHP execution, preventing the page from rendering at all</li><li>Removed debug code (echo/print_r/die block) and user comparison queries that referenced non-existent databases</li><li>Added database existence check before attempting migration queries — checks <code>information_schema.SCHEMATA</code> for <code>demo_youportal_ovh</code> and <code>demoyp_Hvlcty</code></li><li>Shows warning message when migration databases are not available instead of crashing</li><li>Initialized all template variables (<code>$ovhserver_tbl</code>, <code>$tables_array</code>, <code>$total_discrepancies</code>) with defaults so the page renders even without databases</li><li>Wrapped DB operations in try/catch for graceful error handling</li><li><strong>index.php:</strong> Guarded <code>$_SESSION[super_admin]</code> (2 occurrences)</li></ul>
