Magento 管理员给出 500 错误 - 日志中没有任何内容

Magento admin giving 500 error - nothing in logs

我的 Magento 管理员在我尝试安装扩展后停止工作。现在,当我尝试访问 /admin 时出现 500 错误。奇怪的是 error_log 中什么也没有显示。开发者模式日志:

已经尝试卸载扩展程序,但没有成功。我应该怎么做才能找到错误的原因?

请先关闭编译,使用这个:

php -f your_project_folder/shell/compiler.php clear php -f your_project_folder/shell/compiler.php disable

然后清除缓存var/cache。您可以删除此文件夹。
