Fix VPS 500 Error

I’m getting a persistent “500 Server Error” whenever my site is loaded in the browser. The site isn’t WordPress; it’s built on a different framework (think Laravel / Joomla style). The problem began right after I tweaked a server-side setting—specifically a PHP version or web-server configuration change—so I’m confident the issue lives in that layer.

I need someone who can dive straight into the VPS, trace the mis-configuration, and bring the site back online without breaking existing code. You’ll probably review error logs, confirm file and directory permissions, roll back or adjust the PHP or web-server settings, then validate that every route and asset renders correctly in the browser.

Deliverables:
• 500 error fully resolved and site loading normally
• Brief summary of the root cause and the exact change applied so I can avoid repeating the issue

If you’re comfortable troubleshooting VPS environments and frameworks such as Laravel or Joomla, this should be a quick win for both of us.
