Twitter login - looping

[maxmuwidzumga]

I have set up the plugin for Facebook, Google and Twitter login. However, when I attempt to login with Twitter credentials (via Firefox, Mac), a page with a redirect message loops endlessly. I have tried clearing the cache in both my browser, and website backend. When I sign in on my iPhone (safari), this does not happen and I am able to access my website with no issues. Please help. Thanks
