WHY UPDATE
Security fixes Compatibility with WordPress updates Bug fixes
THE RISK
Updates change things. Layouts break.
THE PROCESS
Back up Update on staging first, for anything significant Check key pages Update live Check again
WHAT TO CHECK AFTER A THEME OR BUILDER UPDATE
Homepage A page built with the builder A blog post The contact form Mobile layout
IF A LICENCE HAS LAPSED
Updates stop. The theme keeps working.
That becomes a security risk over time.
Renew, or plan a change.
IF AN UPDATE BREAKS SOMETHING
Revert if you can.
Report it to the developer. Frequently a fix follows quickly.
WHAT NOT TO DO
Leave a theme or builder unupdated for years because you fear breakage.
That accumulates risk. Test on staging instead.
