Reactivating a WordPress site after being hacked

Hi,

After my WordPress site was hacked, I followed the steps below. That is, changing passwords, making a back-up both the database as the content and deleting all content from the server. I reinstalled and copied the WordPress theme I was using and all the image files that were in the folder uploads. Now, it seems that all is well except when accessing the various posts and pages. It’s strange, because in my dashboard I can see all the posts and pages I had. I suspect that there must be some conflict with the database, but would not know how to fix it.

I would appreciate any help. This is the link: https://www.sergioparra.es/
