shapely - will not install

I attempted to install shapely - downloaded the zip file and used the steps in wordpress - plugins- add new - upload plugin - choose file - shapely - install now.
It appeared to upload (percentage increased until it was 100%, but then this message appeared:

Installing Plugin from uploaded file:
Unpacking the package…

Installing the plugin…

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

Plugin installation failed.

Return to Plugin Installer
I read the forums, and it appeared that PHP 4.6 or later is required. I checked with the server provider and PHP 5.3.29 is installed.

What have I done incorrectly? Can you assist?
Thanks heaps in advance.

PS I then downloaded shapely 1.1.2 again and repeated the process. Same result.

Hello there,

I hope you are doing well today.

Are you using the newest version of WordPress?

Please deactivate your third party plugins then try installing the theme once more as it can be the case that one of the plugins is causing an issue.

Best Regards,

Thank you.
It is a newly installed wordpress version 4.9.1 and there are no plugins installed at all. Shapely was going to be the start.
Has this problem ever occurred elsewhere?


Hello there,

I hope you are doing well today.

This issue has not appeared with anyone else so far.

Let’s try this.

Please delete the theme then install it once again then go to Appearance > About Shapely and install the bundled plugins from there.

Let me know the results.

Best Regards,
