Question Fatal Error - Swift_Mime_SimpleMessage is not available

[PaulProe]

We are using DbTech mail and all of a sudden are getting fatal errors. This is a clip of the last one



Any ideas on why this is occurring?

Your version (v4.6.2) is not compatible with XenForo 2.3. You can see compatibility info by going to the releases page here: https://www.dragonbyte-tech.com/store/dragonbyte-mail.342/releases

v5.0.0 is the earliest version compatible with XF 2.3, so you will need to renew your license in order to access an XF 2.3 compatible version
