Reinstalled the Theme 5 times now. Everytime I do it, the Visual Composer included in the theme (The one modified) is not working. Original visual composer does work (the authors one)

This is a JS error I'm getting:

Uncaught TypeError: Cannot read property 'params' of undefined (composer-view.js:245)

And what I see is that where it is supposed to display the page to edit, there is nothing. Althought, if the page is blank (new page) it displays correctly, but if I save the page and re-edit again, blank again.

Could I get some help please?

I see I have 7.0.2 of the Theme.

Going to try to get in touch with my client who bought the theme to get access to the new download.

Anyway, having the purchase code, do I have any option to register it to my self account to be faster?

Thanks

Updated to 7.0.5. (Both Theme and plugin)

Wordpress in last version.

All other plugins disabled.

Visual composer still not working. Errors are:

backend.min.js?ver=4.9.2:4083 Uncaught TypeError: Cannot read property \'params\' of undefined

backend.min.js?ver=4.9.2:4025 Uncaught TypeError: Cannot read property \'attributes\' of undefined

When in a blank page I try to add a row, for example, I\'m getting:

backend.min.js?ver=4.9.2:1984 Uncaught TypeError: Cannot read property \'vc_row\' of undefined
