Hi Iván,
I have checked your old and new sites but didn’t find any differences. If you are still seeing any that might be due to the cache, I would suggest you check once by clearing all types of cache including the Style Cache from Cornerstone > Settings > System > Clear Style Cache and check in the incognito/private mode of the browser.
If that is not the case please provide any screenshot marked with the issue or any video that helps us to recognize the problem. And also provide the login credentials for your site in a secure note to examine it further, including:
– WordPress Site URL & Login URL
– WordPress Admin username/password
To create a secure note, click the key icon underneath any of your posts.
Thanks
