Updates not saving using the theme ENFOLD from Kriesi

I am working on a website using the theme ENFOLD from Kriesi.

In the past few days, when I edit a page (any kind of change, mainly adding text or adding a layout builder saved template) and update, some content is disappearing. It happens on different pages.

I have tried to flush the cache, to deactivate the plugins one by one, to work on a different browser, but still have the same issue. Wordpres has been automatically updated by Siteground on 12-5-24.

Do you think I should update the ENFOLD theme?

If I do so will I lost my settings and pages?

I have installed a child theme too.

You should if there’s any update.

You may, get the backup first
