First, this plugin is awesome and has become essential to my site. I am fighting a very frustrating problem though with Daily Digest emails not sending to most (but not all) users.
I have about 30 plus users on Daily Digest. I moved the website to a dedicated server and since that time most no longer get the daily digest. The website name stayed the same and more confusing yet is there is no consistency. I am not even sure that the server move has anything to do with it.
I have not updated wordpress or a single thing on the site in probably 6 weeks, except I did just recently update this plugin
Here is what I know/checked. I have 2 users that were getting daily digest and no longer are. I have even created a test email account to "live" in between for testing to make sure not a spam issue. They get email when set to All Email, but not on daily digest. I have removed them from the group, re-added them to the group, changed email settings and nothing has worked.
My account, and at least 2 others, are getting the updates. I have worked with hostgator and looked at the mail logs and it appears the emails are simply not being generated.
I am not sure where else to go with this. Is there a way to somehow reset some of these users to re-activate. Is there a table I should refer to? I can go into the group and see them set to Daily Digest and I can logon as them as well and see it, so they look like they are setup right. When I go to the URL test it doesn't show them as waiting to get the email like it used to.
Of course my main concern is the site has 150 users and 30 plus groups with all sorts of different settings, so I can't really lose those settings. Any advice on next logical steps would be fantastic as this is quickly becoming not so good.
