When I try to install VersionPress, it tells me, "The package could not be installed. No valid plugins were found."

Question

I'm trying VersionPress for the first time. I downloaded the project from the VersionPress GitHub page, then went to Plugins>Add New in my dashboard and uploaded the zip file "versionpress-master.zip" and click the install button. Then, when the project starts loading, it takes me to a screen that reads:

Installing Plugin from uploaded file: versionpress-master.zip Unpacking the package…

Installing the plugin…

The package could not be installed. No valid plugins were found.

Plugin installation failed.

Am I doing something wrong? I'm doing this on the version of my site that lives on my shared server, not on my local installation.

Answer 1

It looks like the file you downloaded, versionpress-master.zip, isn't structured like a WordPress plugin. When I unzip versionpress-master.zip, the plugin looks like it's in the directory plugins/versionpress. You'll need to copy that directory and all its contents to your site's plugin directory (usually wp-content/plugins).

Edited to add: The official site's installation instructions indicate that you should download the plugin zip file from their site, not from GitHub.

Edited again to add: The plugin is no longer being developed and does not support WordPress 5.x/Gutenberg.
