Which version of PHP is supported with v5.3.54 ? I had mine set to PHP 8 when using v5.3.46 and it all seemed to work fine.
Today, I went to upgrade to v5.3.54 and rant the update URL with my secret key ( url.com: THE URL Shortener - Free, Custom URLs ). I got a 500 server error with this in storage/logs
/home/removed/billing.elev8your.com/vendor/laravel/framework/src/Illuminate/Foundation/Http/Middleware/ValidatePostSize.php(27): Illuminate\Pipeline\Pipeline->Illuminate\Pipeline\{closure}(Object(Illuminate\Http\Request))

I switched back to PHP 7.4 and was able to run the update URL successfully
