YES…it is possible! Webjunk doesn’t know what he/she is talking about.
1. Download all the plugins you want from WordPress. When you go and search for a plugin and hit activate, you’ll see at the top of the page a WordPress URL ending .zip. Enter that URL into your browser and you’ll get a download window popping up. So download the plugin to your computer.
2. Do this to all the plugins you want to have on all your sites.
3. Create a folder for all your plugins (call it say, “Plugins”)and unzip all the plugin folders into this folder (so the folder has each plugin UNZIPPED). Delete the zipped versions.
4. Now zip the “plugins” folder. Now you’ll have a folder called plugins.zip
5. Go to your host, open File Manager.
6. Go to your WordPress site within File Manager. Then go into wp-content, then plugins folder.
7. Upload the plugins.zip folder from your computer to the plugins folder within wp-content.
8. Right click the plugins.zip folder and select extract. All the plugins folders will be there.
9. You can delete the plugins.zip folder.
10. Now go to the plugins page of wp-admin area of your site and activate the plugins.
All the plugins are separate just as if you uploaded them individually. So if any issue with one, it won’t affect the others….as webjunk indicated.
Hope that works for you!
