Thank you for the prompt update! It’s confirmed, setting WP_DEBUG in the wp-config.php file did the trick. It turns out that my backup file and website were built for an older version of PHP 7.4, not PHP 8.1. After reverting back to PHP 7.4, the (All-in-One WP Migration) backup worked perfectly, and the issue is resolved.
Now, I’m facing the task of upgrading some plugins and my website to PHP 8.1. Do any of you know of any automation scripts or converters that can streamline the transition from PHP 7.4 to PHP 8.1?
So, if you ever find yourself stuck at a certain backup progress percentage, remember to check your PHP version! I spent three days scratching my head over this. I hope this information proves helpful to others facing a similar situation. ????
