After moving my PHP-based site to HTTPS the payment “success” endpoint has started rendering a completely blank page. Nothing shows in the browser, yet the same page worked perfectly before the SSL certificate went live. I already enabled full error reporting and combed through both the server and PHP logs but no warnings or fatal errors are being captured. The checkout flow still reaches the URL, it just presents white space. Because the problem appeared the moment SSL was installed I suspect an HTTPS redirect, mixed-content block, header or session issue—but I need an experienced eye to confirm and resolve it quickly. Deliverables • Diagnose the root cause of the blank success page under HTTPS • Apply a clean, secure fix in the code or server configuration • Demonstrate the page loading correctly over SSL without breaking any other part of the checkout flow I can provide SSH or cPanel access, payment gateway callback details, and a staging environment if preferred. Please let me know your estimated timeframe and any similar SSL-related PHP issues you have solved so we can get this wrapped up today.
