Enhancement: show a notice and link to clear the cache when the theme is changed #31859

Open donnchawp opened 1 year ago

Impacted plugin

Super Cache

What

The plugin should show an admin notice and a "clear cache" button when the theme is changed

How

As mentioned in this post, WP Super Cache does not clear the cache when the theme is changed. I believe this is the right thing to do because the theme may be changed to test a new one temporarily. However, an admin notice containing a "Clear Cache" button on the themes page that appears when the theme is changed would be a nice shortcut.

If caching is enabled for logged-in users, we should display an admin notice on the themes page informing the user that the cache must be cleared manually.

Could we instead have an option for the SuperCache to invalidate if the theme/plugin or their versions change? Any plugin or theme change could invalidate page content.
