[Plugin: Custom permalinks] 301 loop when custom permalink ends with a forward s

Hi,

when i set up Custom permalink that ends with a forward slash i get an 301 redirect loop.

so if is set up a custom permalink like this https://www.domain.com/dir/url/
and go to it in the browser tht loop looks like this

https://www.domain.com/dir/url/ –> 301 redirect
https://www.domain.com/dir/url –> 301 redirect
https://www.domain.com/dir/url/ –> 301 redirect
https://www.domain.com/dir/url –> 301 redirect
ect..

if i set up the custom permalink with out the slash on the end it works fine.

How can i get it to work with the slash?

Thanks
