We have a shop created with 1.6.1.6. It uses PhpMailer and it worked perfectly. When we decided to move the shop from shared hosting to a VPS I decided to update it to the latest version using i-click update module. The new version 1.6.1.9 However the update did not work, the error message was something about the Adapter folder so I rolled it back. At the same time, the shop stopped sending out emails, Error, please check your config. I moved the shop to the VPS but the error is still there, and I suspect something happened during update and roll back. As a notice, the other shop on the VPS works without a problem. Anyone knows what may have happened?
