1. You can use https://wordpress.org/plugins/all-in-one-wp-migration/ to move the content to a new wordpress instance.
2. I don't know if it will work.
Seeing that you can not help me....
1. Is there any way to copy the already loaded properties to a new theme from scratch?
2. I'm working in local using Local by Flywheel, if I share you the link you can check the problem?
No, I used the file from the zip I downloaded from Themeforest...
Do you use the child theme that we have included or you created one?
We recommend you to use the one that is included in the folder you downloaded from themeforest.
I'm developing the site in local. What we can do?
Can you send login credentials to take a look?
I need help with these, I really don't know what to do here. Do you want I send you the files of duplicator of site by wetransfer and you take a look? Thank you
Yes, it worked.It doesn't recognize the logo and the styling of the website, but there is not a problem with that, it doesn't take so long.
But I've made a search and the result is the attachment. So weird... Do you know what it could be?
As I can see from the capture you need to install the casaRoyal plugin which comes with the theme.
Let me know if it worked.
I irresponsibly created a website in the pattern version of the theme. I want to change to the child theme, so I follow this steps https://www.youtube.com/watch?v=ebGrw1h6Hog
And when I choose the child theme everything breaks and goes to the original theme. What should I do?
