Today, we saw that WordPress Redirection plug-in has a new version that can be upgraded. Here, after clicking Manual Upgrade in the background, we found that the "Cached Redirection detected" error was reported on the plug-in page.
You can also see that the list of 301 redirected URLs below cannot be opened. You can see that it is caused by the cache. You need to refresh the file here.
We check whether the website has a CDN or cache, and if so, we need to refresh it:
wp-content/plugins/redirection/redirection.js
This page.
The problem is solved after refreshing.
