我在网站上看到这个错误.....我真的不知道如何解决这个问题，因为我不是php的专家：/
这就是我得到的：
警告：require（/www/opencart1/fifafinity/comfifafinity/adminpanel123456//adminpanel123456/files/core.php）：无法打开流：/ www / opencart1 / fifafinity / comfifafinity / adminpanel123456 /中没有此类文件或目录第4行的index.php
致命错误：require（）：未能打开'/www/opencart1/fifafinity/comfifafinity/adminpanel123456//adminpanel123456/files/core.php'（include_path ='。：/ usr / local / share / pear'）在/www/opencart1/fifafinity/comfifafinity/adminpanel123456/index.php第4行
如果有人能解释我如何解决它会很棒，谢谢！
