WordPress Theme, PHP & Photo Recovery

My site is still running Jupiter Theme 5.9.2 on WordPress 6.x and PHP 7.4. I’m ready to upgrade, but I do NOT want to abandon Jupiter—just bring it to its latest stable release so everything stays visually consistent.

Here’s what I need handled:

• Theme upgrade: move Jupiter from 5.9.2 to the newest supported version while keeping all existing design settings intact.
• PHP hardening: raise the server from 7.4 to a secure, supported release (security is my top priority) and verify the site and all plugins still run smoothly afterward.
• WPBakery fix: the last attempt to update Visual Composer failed, forced me to deactivate it, and several images disappeared as a result. I need the plugin fully updated and every missing photo restored.
• Final check: confirm there are no broken links, missing media, or layout issues once the above work is complete.

I can provide cPanel and WordPress admin access along with any backups currently stored on the server. Please let me know your plan for staging, rollback, and how you intend to recover the lost images before touching the live site.
