Hi @jimenagordillo,
I checked the page in question and found out that there is additional CSS code added into the source code which is not part of our theme:

It says Cache Created For: 2 as comment
I am not sure where the code comes from but that is causing the color of all text to be white and the background of your website is also white, that is why you do not see the text at all.
- Test for a plugin conflict. You can do this by deactivating all third-party plugins, and see if the problem remains. If it’s fixed, you’ll know a plugin caused the problem, and you can narrow down which one by reactivating them one at a time.
- Remove custom CSS and Javascript from the options and/or Child Theme and test the case.
- If you’re using a CDN, please clear the CDN’s cache and disable optimization services.
kindly get back to us with the result of the steps above and URL/User/Pass of your WordPress dashboard using the Secure Note functionality of the post to follow up the case if you still have problems.
Thank you.
