        ⭐ Upload a working version or change file permissions if needed.

    2️⃣ .htaccess Reset – Could the file be misconfigured?

          ❗ Important Notes     

▪️If your website works in incognito mode but not in a regular tab, the issue might be due to a cached error. Clear your browser cache and try again.

▪️The maximum memory limit on shared hosting is 512M. If your site needs more, you may need to upgrade to a VPS.
