I just downloaded the newest Classipress version 3.2.2, went into a new fresh install of WordPress 3.8, went to Plugins, Install New, browsed to the the downloaded file, uploaded it, clicked install and got this error:
Installing Plugin from uploaded file: classipress-3.3.2.zip
Unpacking the package…
Installing the plugin…
The package could not be installed. No valid plugins were found.
Plugin install failed.
What am I doing wrong?
