The seller immediately started the diagnosis of our issue. After some time he had found the first issue. He patiently asked for a good time to performance maintenance, which required rebooting. Unfortunately the issue couldn't been resolved that easy, but after a second attempt the issue has finally been found and mitigated.

Mominul successfully migrated our WordPress/WooCommerce site to a new server environment, handling database transfer, DNS switching, SSL setup, and live validation. The migration was completed and the site is running smoothly on the new server. I appreciate his technical support throughout the process.
