If you have an existing website and you want to add category to your blog posts links (e.g. by using: /%category%/%postname%/ in Settings > Permalinks) then your visitors 
will most likely run into page not found errors. This plugin checks for such post links and redirects the visitor using permanent (301) redirect to the correct /Category/Permalink link IF the permalinks are setup.
This plugin assumes that you have previously used /%postname%/ in your Settings > Permalinks.

Permalinks to Category/Permalinks

While it may seem trivial, switching from permalinks to a prefix using a category is tough. Slavi's plugin works just as expected and works out of the box. Definitely recommended.

Works as expected, thanks!

The plugin automatically redirects users who have accessed a blog post link without the category to the one which has the category and therefore avoid …

This is a tool to understand your rewrite rules (“Pretty Permalinks”). It is indispensable if you are adding or modifying rules and want to understand how they work (or why they don’t work).
It is only an analyzer, it does not change any rules for you. It parses the rules down to their components and shows the connection with the resulting query variables. It allows you to try out different URLs to see which rules will match and what the value of the different query variables will be (see screenshots).
This plugin was written as a tool to help answering questions about rewrite rules on <a href="http://wordpress.stackexchange.com/" rel="nofollow ugc">the WordPress Stack Exchange</a>.

Monkeyman Rewrite Analyzer

Throws a warning if WP_DEBUG is on, other than that still a very handy tool to check your rewrite rules.

Very useful

Helped me sort some issues with the rewrite rules when developing a plugin. Works fine with WordPress 5.2 and does what you need it too.

Works Great
