jasonhayward on "WPSiteSync for Content is not installed and activated on Target site"

When I sync a post I get the following error message in SiteSync:

"WPSiteSync for Content is not installed and activated on Target site"

However the plugin IS installed and activated on the target site and most of the content (apart from the images) have synchronized.

How can I stop the error messages and get the images to sync?

Hello Jason,

We would like to gather some info from you. Are you using any security plugins, coming soon plugins, page builder or a theme containing a page builder.

Hi ServerPress,

No both sites are testing sites and only have your plugin installed.
