My email templates are broken after upload/update, what can i do?

You can try to open the file:

apps/common/config/main.php

and look for:

// use tidy for templates parsing
'email.templates.tidy.enabled' => true,

then edit this code part and make it look like :

// use tidy for templates parsing
'email.templates.tidy.enabled' => false,

Save the file and try uploading your templates again.

Please note that MailWizz makes use of PHP’s Tidy extension since version 1.3.6.5.
