Hi @carlosgumiel.
I can’t do it because I came back to the previous version, my WordPress is based in this “all Products” block. The error in my frontpage is.
You mean you rolled back to a previous version of WordPress, or a previous version of something else? What did you roll back, and what were the versions before and after the rollback?
This is most likely a code conflict of some sort. You can use the Health Check and Troubleshooting plugin to test this. The “troubleshooting mode” of this plugin will allow you to simulate how your site would look and behave with plugins disabled and a default theme without actually changing the site.
These are the steps you should take:
1. Back up your site. Many hosting providers offer a way to do this, and there are plugins such as WP Database Backup that offer this functionality if backing up your database through your host is not an option.
2. Update all your plugins and your theme to their latest versions and see if the problem fixes itself.
3. Turn on Troubleshooting Mode in the Health Check plugin by going to Tools > Site Health > Troubleshooting and clicking “Enable Troubleshooting Mode.” Then, while in Troubleshooting Mode:
4. Make sure your theme is set to Twenty Twenty.
5. Make sure all plugins are deactivated, and then activate WooCommerce.
6. Repeat the action that is causing the problem.
If you’re not seeing the same problem after completing the conflict test, then you know the problem was with the plugins and/or theme you deactivated. To figure out which one is causing the problem, reactivate them one by one, testing after each, until you find the one causing conflict.
