You gave the url redirect and it works fine on one dev site that is on the same host but different server

I cant find the difference .

The php trim rule you gave me works fine on both

the rule you gave me auto changes any url from "blog" to blogs" on my dev site 1
devmodjune1.homehighschoolhelp.com
But not on my other dev site 2
keystothenet.com/hhh2020

My dev site 2 is a clone of my dev site 1
Notice it correctly adds the character "s" to "blog' to make "blogs"
devmodjune1.homehighschoolhelp.com/blog/help-for-homeschooling-middle-school correctly redirects to devmodjune1.homehighschoolhelp.com/blogs/help-for-homeschooling-middle-school

However keystothenet.com/hhh2020/blog/help-for-homeschooling-middle-school does not redirect properly to keystothenet.com/hhh2020/blogs/help-for-homeschooling-middle-school

Both rules look identical and I copied and pasted to make sure this is what I have below

From: ^/blog/
To: {scheme}https://{siteurl}/blogs/{pathltrim /blog/}{queryfull}

Thank you
