Ok, Excuse I found the solution in the FAQ site
3. Question: When I follow the instructions to allow your plugin authorize/access to my Facebook/Twitter/Tumblr/LinkedIn account, it redirects me to the “Blank†page, “You do not have sufficient permissions to access this page†message, “Google Analytics for WordPress Configuration†page, or some other plugin†page.
Answer: It’s a known issue that we can’t fix. “Google Analytics†and some other plugins hijack the authorization workflow. Please temporary deactivate “Google Analytics†and/or all other plugins (“Blog Promoterâ€, “Tweet Old Postâ€, “Simple Facebook Connectâ€, “Simple Twitter Connect†etc.. ) related to “Social Networkingâ€, do all authorizations and then activate them back.
