Ok so im not sure if its the current updates of the new events manager plugin fixed the problem or not, but after installing custom post type ui I did exactly as you said and made a post type named "portafolio", I then checked on the status of my regular custom post type of portfolio, and it turns out they now work.
To ensure the plugin was the reason for the post types working I deactivated the cpt ui plugin and the original post types are still working.
I am not sure if it was you guys marcus that made the post types working or if CPT UI somehow miraculously fixed some stuff after installing to fix all the post types again or not but it worked and I am happy.
Although, I do need to mention that my theme and the problem i had if not being solved miraculously by itself after an installation of CPT, CPT would not solve my problem.
Because my theme has built in hooks and information in the custom post type "portfolio" that it uses in the theme to make the intended result work, just a bit of info for you guys developing this plugin to think about.
Finally after thanking you for your help marcus, I would like to make a suggestion to the plugin not related to this issue,
In allowing the cancelation of bookings it would extremely beneficial if we can set the amount of time a user/guest has to cancel their booking, before the start of the event.
IE customers can only cancel their booking if it is 12 hours before the start time of the event.
So in recap CPT has "solved" my problem but not in the way it was intended to per your suggestion and other past use cases. At least not with my theme, as of now I don't have the cpt plugin activated and my post types still work.
Thanks again for your help Marcus
