Hi Peter. Can you check your email because I replied to your request on there. I was asking which plugin you were having trouble with. Any plugin that is on WP.org. you can add by simply using the actual plugin slug from WordPress.org. Example is using wpcore for this plugin and so on.
The custom plugins work differently. You have total control over them and they do not connect with WP.org so there is no reason to add a custom plugin if it is already on WP.org. Please let me know what plugin you cannot find.
Peter I am sorry I just checked and I replied to the wrong address for your email request. I have resent it to you directly.
I will mark this ticket as resolved now. The issue is that sometimes our autosuggest doesn’t pick up the plugin form the name. The quick workaround is to use the plugin slug directly. Just enter that into the box when you are adding a new plugin and ignore the autosuggest.
