Tried updating the Easy CSV Importer in WP admin.
Received message that plugin folder contained no content.
WP deleted plugin, but could not re-install since there was no content to install.
Subsequently went to WP Plugin Repository and downloaded version 6.2.5 of the plugin. When I unzipped it, there was a folder inside. That's it. No files or subfolders, just a containing folder.
I tried this twice with the same results.
I'm wondering if it's just something on my end or if there's something actually wrong with the download file.
