Plugin breaks on upgrade to 4.5.2

Hello,

I am a developer.

I have a wordpress plugin with which we can create compound URL and it reflects on the page.

It used to work fine for the older versions but when i upgraded my setup the functionality seems to be broken.

it works fine for inner pages but does not work for home page

it removes the string “taylor” automatically.

I am not getting what exactly is changing after the upgradation.

when i went through some forums, came to know that 4.5.2 has broken the functionalities of many plugins which work fine on the older versions.

Thanks in advance.
