I’m getting the same thing. WP Users plugin will not update and I get the Not Found information when I try to view the plugin’s details. I have removed and reinstalled the plugin and that doesn’t resolve the issue.
Hi, there was a version number mismatch, could you try again? Please, enter the Newsletter main settings and save before check for updates: that resets the version cache.
That did it. The update took this time. FYI it still says plugin not found when I view the details on the plugins page. So there may be more to this. Thank you.
Sorry, I was referring to the plugin detail link. Did you save the Newsletter main settings?
After that, you can (or not) see an update notice in your plugin list panel, and the update should work.
