Hello Syalih,
The RSS Post Importer Nerd here. Thank you very much for reaching out, I see that you seem to have the same issue with RSS Post Multi-importer or did you confuse the forum, because I see the same questions everywhere : https://www.evernote.com/shard/s268/sh/0ee1af7a-0ec3-4f67-bfa1-773e80910914/1c2657b089ed570899fc58d11947a552 Please let me know. Uninstalling a plugin is quite straightforward, there’s no extra step to take to uninstall any plugin, I believe the process is the same for almost all plugins but can’t describe it here as it will take a lot of time and text, but the short version will be to navigate to your plugin admin UI, de-activate the plugin, then delete it. 3 Clicks should be fine.
Hope this could help.
Sincerely,
The RSS Post Importer Nerd
