It appears to be a problem with the Events Calendar plugin. After, I disabled it, the comments are working. I tried reinstalling back to previous version and it crashed the whole site. I opened a ticket support request from the Events Calendar plugin for further support.
Thank you for your support,
These options used to appeared in the Appearance [Menu]. If you go to my website (http://ventureouterzone.com), and not logged in, you'll noticed there is a Profile menu. The profile menu had a Menu Type option to hide to logged out users. That option is no longer available. I'm not sure whether if these were theme options before but I have tried reinstalling the theme, I could not get the menu type options to come up. I attached a couple of screenshots from my first post. [attachment=1186854,105601]. WPMU DEV support access has been granted :).
Will do...thank you. Sorry I got panic and couldn't get the website back up running :). I was trying to change the custom post type for the events+ within the theme and it broke the whole site. Thank you.
