I am using tubepress since two years, but recently I got the Http 410 no longer available error. I followed instructions to install the 4.1.9 version. 1. I removed the old version, 2. I Downloaded TubePress as a zipfile to my desktop. 3. Unzip the file. 4. uploaded the unzipped folder to the wp-content/plugins folder in my WordPress directory online.
Nevertheless, the plugin do not appear in the plugin list so I could not activate it.
