Hello, I have strong experience with Typo3 and PHP upgrades, including moving sites to newer PHP versions while keeping them stable. I understand how stressful it is when a site stops working—pages don’t load, the backend is broken, and extensions fail. I can carefully check your test server, fix all errors, update extensions, and make sure the database and code work properly on PHP 8.2. I will also document everything so you can see exactly what was done. My goal is to get your site running smoothly again, remove all errors, and make it ready for the Typo3 13 upgrade. Thankyou, Azad

Hello, I've worked extensively with Typo3 and PHP upgrades, including transitioning between major PHP versions while ensuring CMS stability. For example, in a project involving an e-commerce platform, I resolved compatibility issues by meticulously updating custom extensions and optimizing database interactions for PHP 8.x. Given this background, I would begin by analyzing the error logs on your test server to identify PHP 8.2 compatibility issues within your Typo3 installation, focusing on deprecated functions and extension compatibility. This approach ensures both backend and frontend stability before proceeding to a full upgrade. Let's discuss!

Hi, Ich werde die Probleme auf deinem Testserver mit Typo3 11.5 und PHP 8.2 schnell analysieren und beheben, damit das Backend und Frontend stabil laufen. Ich habe umfangreiche Erfahrung mit Typo3-Upgrades und PHP-8.x-Kompatibilität, sodass ich die Fehlerursache zügig identifizieren kann. Mein Ansatz wird eine gründliche Überprüfung der Konfigurationen und Extensions beinhalten, um sicherzustellen, dass alles reibungslos funktioniert. Ich arbeite dokumentiert, sodass du alle Schritte nachverfolgen kannst. Nach der Fehlerbehebung liefere ich einen Kurzbericht, eine Übersicht der durchgeführten Fixes und einen Abschlusstest, der die Funktionalität der Seite bestätigt. Sobald alles stabil ist, können wir nahtlos mit dem Upgrade auf Typo3 13 und der Datenbank-Migration fortfahren. Ich freue mich auf die Zusammenarbeit und bin bereit, sofort zu beginnen. Vielen Dank.
