这是后端url

当PS_MODE_DEV为true时，我得到：

感谢您提供的任何帮助

对我来说似乎是Symphony缓存问题-尝试清空整个/app/cache/文件夹，看看是否有帮助

另外，/app/cache/文件夹来自buggy 1.7.2.x所以我已经清除了整个APP/Cache /文件夹，并将PHP版本降为7.2，现在只剩下一个错误：AdMyAdHealDraveCulr.php行29中的FATAALError异常：编译错误：AdMyStubBoDigabrMeCule:：StIdMIAL（）的声明必须与Admin MealthReCy:：（$isNewTheme=false）好的，我已经解决了它降级到PHP7.1的问题，谢谢你的帮助！
