Permissions denied in admin dashboard

Hello all,

I have installed the membership plugin and everything worked pretty well, until today. When I logged in to my admin panel I only could see the dashboard, profile, and membership plugin, I have access denied for the rest of the content of the page. Can't see the other plugins.

Lately I have installed the yoast wordpress SEO plugin, the w3 total cache plugin and the xml sitemaps plugin,I don't know if can be any conflict.

Any advice to solve it?
