My Magento storefront has suddenly begun throwing a 500 error on the homepage. The issue appeared without any code or extension changes, but I did adjust server settings just before it happened—specifically, I altered some file permissions. I need an experienced Magento developer who can jump in, trace the exact cause, and restore the site to full working order today. You’ll have SSH / cPanel access (including error logs), and I’m happy to roll back any permission tweaks you identify as problematic. Once the front-end loads cleanly again, I’d like a brief summary of what went wrong so I can avoid repeat outages. If you’ve handled similar Magento rescue jobs, especially those stemming from permission mishaps, you should find this straightforward. Let’s get the store back online as soon as possible.
