Plugins: add redirect for a single plugin page for a wpcom site, when switching from a self-hosted site

[v18]

There is no redirect from https://wordpress.com/plugins/akismet/yoursite.com to https://wordpress.com/plugins/yoursite.com. So, when a user attempts to switch from a .org site to a wpcom site on a single plugin page, they see a 'not supported' message.

Steps to reproduce:

1. Go to a Jetpack site that has Manage turned on, and view one of the plugins (either installed already or not). Here's the URL:
   https://wordpress.com/plugins/akismet/yoursite.com

1. Click on 'Switch site' and select a wp.com site instead. Note that the URL changes to this:
   https://wordpress.com/plugins/akismet/wpcomsite.wordpress.com

This is what it looks like for both business & non-business users.

The issue here is that the user should be redirected from https://wordpress.com/plugins/akismet/yoursite.com to https://wordpress.com/plugins/yoursite.com

that was the behaviour we had some months ago ... I think it was quite confusing, since the user was redirected without warning... I wouldn't change it back and I would keep the current error screen... ping for thoughts, @enejb @MichaelArestad @rickybanister @beaulebens

Yeah, this is a little bit tough—I think the best we can do here is swap this rather generic error message for something more helpful:

• A preview of what plugins you can use for business sites (the content preview thing)
• An advert for upgrading to Business for non-business sites (similarly mentioning that you can unlock ecommerce plugins that way)

Basically if the error message is more tailored I think it's ok to redirect. Or if we leave the url the same, we can still show a more helpful error.

It seems like we should just do some further testing on this (there's a store test going right now to display a message similar to what I suggest above) and then we should be able to close this issue as 'wont fix'

I agree with @johnHackworth here since. This I think the current implementation works quite well.
I think maybe improving the messages such as. If the user is on a business site and they land on a .org plugin. They should see an action button that would take them to their list of sites.

I am moving this out of the current milestone for now. Since we have no clear idea how to fix this yet.

This is working as expected now, after recent launch of WordPress.com plugins page in Calypso.

I used steps above, and after going from Akismet page for Jetpack site to a WP.com site, I end up at a URL like https://wordpress.com/plugins/lancetest35.com which is accurate.
