Hi Barry,
Thanks for your response. My steps were the same as yours with different results, as you noted.
We are using very few plugins on this site. In addition to All in One SEO, we are using:
Duplicate Post by Enrico Battocchi
Redirection by John Godley
404page by Peter Raschendorfer
Jetpack
Our theme is Enfold, which was supposed to be compatible with The Events Calendar. We do not have a staging site for nyharborparks.org, so cannot risk changing themes, to test. (It might be impossible to restore the design intact when we switched back.)
I went back to the post about the same problem on your forum — https://theeventscalendar.com/support/forums/topic/og-image-description-entries-ignored/#post-1373236. I discovered that that site uses a different theme — parallax.
The post says social meta tags produced with All in One worked for Tribe events until 12-18 months ago, then stopped working.
The response to the post says that switching to Yoast solved the problem. If true, that suggests that there is indeed an incompatibility between All in One and The Events Calendar. Is this something you could look into, given how large the All in One user base is?
Thanks,
Sheryl
