I have the same problem, but Im so new at this; I have no idea how to open any console and look for js errors. The plugins I have are akismet, contact 7, theme4press core, wordfence, captcha, and revolution slider. Not really sure what to do at all. The pro version looks awesome, but I want to ensure the free version works.
I am using wp4.1 with alora thema. Thank you for any guidance you may provide. Jason
