Extra ‘/’ in URL for index.php

I am having a problem viewing my blog pages when I use the ‘View>>’ link in the Write post part of WordPress.

I have wordpress installed in a subdirectory of my site as the I have a php script installed for the main site. So, I need to keep it separate from the root directory.

The problem I get is when I click on the link it tries this url:

https://www.mysite.com/wp/index.php/?p=21

As you can see an extra ‘/’ is appearing in the url after the index.php

My site url in the wp Options is set to :

https://www.mysite.com/wp/index.php

Because otherwise, https://www.mysite.com/wp yields me a display of no pages. I have to include the ‘index.php’

Any help on this would be highly appreciated…

Thx!
