brianct-

I feel your pain. Within the past 6 months or so I fully embraced MainWP while ditching some other more expensive management options for WordPress sites. I have about 60 sites, all with similar plugins that work great. One of which is Post SMTP that i’ve been using for over a decade with very little issues in conjunction with ElasticEmail (and their API sending feature).

Thought i’d give the MainWP Post SMTP Extension a go because all my child sites are managed by MainWP and Post SMTP is fully functioning on each site normally. Followed the basic (aka rather limited) document and saw all the sites appear under the add-on section of MainWP. Figured we were good to go, however I’ve discovered that now NONE of my sites are sending emails anymore.

Try sending a test message to find what you described:
Your message was delivered (0 ms) to the SMTP server! Congratulations 🙂

There is no transaction log it is just blank. Obviously activity on the SMTP relay side shows nothing, because WordPress no longer appears to be sending emails out of the platform anymore.

In a panic I uninstalled MainWP Post SMTP Extension which partially removed. It appeared to get “stuck” because it no longer showed up on the WordPress Admin side of my MainWP install, but if you searched in the WordPress repository it would appear as “Update” and subsequently “active”. The whole install appeared to be broken. Rather than sift through databases and try to do cleanup tasks, I restored from backup and relaunched my MainWP instance to see if that would take care of the problem. It did not, but I was able to narrow down where the issue was.

The temporary fix for this is to deactivate the MainWP Child plugin on the child sites. This allows Post SMTP to continue working as it once did. All my tests began working just fine in this state.

The big problem now is that none of my sites are being managed by MainWP for plugin updates, etc. This is a big wrench in my overall support strategy for all the sites I manage. Sad face.

I’ve attempted to disconnect sites, reconnect them. Even uninstalled Post SMTP and reconfigured it from scratch but can’t get the “original” combination of MainWP management, WordPress site with MainWP child installed, and Post SMTP locally on the child site, to send emails.

Any chance someone can look into this either on the MainWP side, or the Post SMTP side to figure out why this stopped working? Here’s a system status dump from one of the affected sites.

I’ll subscribe just to see if anything updates here.

I have noticed his behavior as well. For example if you change the font to “increase text” I would expect that as you click through to the next link / page on the site that the larger font size would still be in effect.

I am not seeing the settings held on the next page visited. Is this a misconfiguration on my part or a limitation of the plugin?

This would be a really nice feature to have. Hopefully it will be in a future release!
