Repair WordPress Site Malfunctions (Avada theme)

My WordPress site went south after I made a few edits. The homepage no longer renders correctly and the theme behaves unpredictably; even the backups I keep in the hosting panel now restore in the same broken state, so something I changed seems to have propagated into every snapshot I try.

What I need from you
• Diagnose the root cause on WordPress core, database, theme files, or server settings.
• Roll back—or manually rebuild—whatever is required so the homepage and theme display exactly as they did before the issue appeared.
• Verify the fix persists by creating a fresh, clean backup that I can safely fall back on next time.

Notes you’ll want to know
– Platform: WordPress.
– Affected areas: Homepage, Theme (back-end “revisons” also appear corrupted).
– No recent plugin installs on record, but you’re free to rule out plugin conflicts if that speeds up a clean restore.

Once the site is stable, just hand over a brief summary of what went wrong, what you corrected, and a tested backup archive. If this sounds straightforward to you, let’s get it done.
