The following problem occurs at my site occasionally. I don't know the reason yet.
After some point new emails are sent only to newly added users. The old users are ignored with "No mail content to send" notification. After I simulate the given date for the ignored user ID, the simulation shows that new content. It does help when I Sync all th users with the following options:
- Show Advanced Sync Options
- Overwrite Existing User Preferences
I know that I should Sync at some changes. But I didn't do any of the following lately:
- adding a new plugin tag in email alert template
- changing default values in one of the plugin's 'legacy parameters / options'
If there is any other trigger I'm happy to remember it. But I would like just to set Sync every time I log in or log off my site... That happenned so many times and some of the users of my small site didn't get the proper messages.
