my portfolio/ page link rebounces back to home instead

I need to speak with the devs because this plugin has created some sort of mask on my portfolio page… whereby it bounces/autoredirects the user to the main page when clicking /portfolio/ link… i deactivated the plugin and I am left with this issue… i have altered menu labels to projects page as a result but the client wants the portfolio/ link to wor. Please help if you know of this issue…
