<h4>Profile Page &amp; Menu Card Fixes</h4><ul><li><strong>Fixed:</strong> Undefined array key "connection_filter" in user.controller.php line 966/968 — getAllFollowersSummary() accessed $r["connection_filter"] without null check when called from profile page. Added null coalescing.</li><li><strong>Fixed:</strong> "Trying to access array offset on null" in user.controller.php line 1250 — check_acct_block() returns null when no block record exists, then code accessed ["id"] on null. Added null check with fallback to 0.</li><li><strong>Fixed:</strong> Three cascading warnings in get_menu_card_per_item.php line 76 — $module[$strIncludeFileID] accessed when the include file ID is not in the module array (only products/services IDs 35/36 are defined). Added isset() guard around the entire block.</li></ul>
