Fix Broken Jupiter X WordPress Site

veggioke.com lost its proper layout right after the last round of automatic core and plugin updates. Pages now look scrambled, even though I never customized the Jupiter X theme or any plugin files.

What I need is straightforward:
• Pinpoint whatever conflict or update glitch is causing the layout issues.
• Bring every plugin and the WordPress core up to their latest stable versions once the conflict is resolved.
• Switch the site to the most recent stable PHP release.
• Deliver the repaired site looking exactly as it did before the problem, with no broken styling or missing sections.

Please be comfortable digging through Jupiter X settings, isolating plugin/theme conflicts, and working directly on a live production site (I can clone to staging if you prefer). A short summary of what went wrong and the steps you took to fix it will be the final hand-off.
