Problems with Siteorigin Corp theme + Siteorigin page builder plugin

Hi,

I installed Corp theme and page builder plugin (+ widgets bundle + siteorigin CSS) on localhost and everything works fine.

I uploadad everything my website using Duplicator and the problems started.

I can´t customize the theme using the Customize option, the screen gets blank, only the ‘You are customizing …’ text.

The pages or posts editor doesn´t work, only the ‘visual’ and ‘html’ tabs are shown, the ‘Builder’ tab is missing, and nothing works, so you can not edit the pages or posts.

I have turn off all the plugins (except the siteorigins) and still get the same. If I turn off all the plugins, including siteorigin´s, everything works (but I can´t use the page builder plugin).

If I change the theme everything works but I can´t use the corp theme.

I´m running a WP 4.9.2 and all the plugins are updated. I also have cleared the cache several times. The PHP version is 7.0, the memory limit 256M.

The point is that I can use the theme, it´s running, but I can´t change anything because the pages/post editing is not working or the customizing is neither working. I´m afraid that I should change the theme, but I would like to ask you if you have any clue about what´s happening.

Thanks for your help and for creating such awesome tools.
