strip out the tag base

Looks like you’ve just copied someone else’s question exactly from 3 years ago: https://www.ads-software.com/support/topic/plugin-wordpress-seo-by-yoast-remove-tag-base-permalink?replies=2

You could at least look at the suggestion in that thread if you’re going to copy the question: https://www.ads-software.com/extend/plugins/wp-no-tag-base/

without plugins , is there any method ?

will be to use functions.php and some regex

but striping /of tags is dangerous.

did sisbi told you that? also yoast is just a common guy
thing. like if having a great seo is done by a
free plugin.

many methods without plugins, yes.

but not a good talk for it :p^
