I already fixed the problem! i just used the plugin “search and replace” but in the field where you have to write the URLs to correct them, you have to write them in PHP language, for example:
http%3A%2F%2Fgersanchez.com%2FotrapruebaWordpress
instead of this
https://gersanchez.com/otrapruebaWordpress
You can see how your site URLs are written in php when you search them in your .SQL data base, opening it with any text editor like sublime text.
that is all.
