I’ve taken over running a site with the Newsletters plugin from someone else and am having issues with viewing the past newsletters and sending new ones.
I’ve done a search on here and on Google and haven’t found anything that seems to solve the problem I’m having.
When going to the Newsletters page, there’s a message that “Your Newsletter installation has emails still in old format. To get them listed, you should convert them in a new format. Would you to convert them now?” followed by a “Convert Now” button. Clicking the button just results in a “Database error” with no further information.
Does anyone have any ideas about what can be done to convert the emails or how to fix this?
Plugin version: 3.9.7
Wordpress version: 4.3.1
Thanks everyone.
