Issue with my URL path after downloading a Plugin

Hello everyone,

First of all thanks to the WP community for such a great tool. I recently started a blog site and after I installed a plugin my website stopped linking to my articles correctly.

I also tried changing the permalinks to a default setting but even after I reset to the default settings the path continue to be broken.

The main site is https://www.spectrumdesigns-dc.com/

and the blogging section is here https://www.spectrumdesigns-dc.com/blogsite

When I hover a recent post (ipad 2 vs xoom) I see the path at the bottom that shows….. https://www.spectrumdesigns-dc.com/?p=7

And the actual link should look like….. https://www.spectrumdesigns-dc.com/blogsite/?p=7 is missing the /blogsite/ path.

Please help me, I tried restoring some files (not all, yet) from an earlier backup with no avail.

Thanks to everyone in advanced.
