phpMyAdmin 致命错误:调用未定义的函数 __()
运行 RHEL 7 和 PHP 5.4.16 的服务器.当我尝试在浏览器中打开/phpMyAdmin 时，出现错误:
致命错误:在第 242 行调用/usr/share/phpMyAdmin/libraries/core.lib.php 中未定义的函数 __()

有人可以根据那个调用堆栈给我一个提示吗?以下是堆栈跟踪引用的行中的函数，相关行写在左边距中:

查看 Config.class.php 中的 checkConfigSource() 函数让我相信，如果问题出在访问配置文件上，那么我会收到错误 'Existing configuration file (%s) is not readable.' 而不是 Call to undefined function __() 有谁知道为什么不是这样?>
这是一个非常基本的问题/解决方案，但除非有人提出其他建议，否则我想我会放弃它，因为在 致命错误:调用未定义函数的其他讨论中没有解决这个确切的问题/解决方案__() in/usr/share/phpMyAdmin/libraries/core.lib.php 安装后尝试启动 phpMyAdmin 时出错.
Server running RHEL 7 and PHP 5.4.16. When I try to open /phpMyAdmin in my browser, I'm given the error:

I believe I've installed all required libraries and that apache has the proper permissions for the session.save_path directory, which were the issues previous times that this question had been asked. See: Call to undefined function __() error - phpMyAdmin
Can someone give me a hint based on that call stack? Here are the functions from the lines that the stack trace references, with the relevant line written in the left margin:

解决方案
The problem was the wrong permissions for the /etc/phpMyAdmin directory. The web server user, apache, had proper permissions for the session.save_path directory, but apache couldn't read from my config.inc.php file. Changing the owner of /etc/phpMyAdmin to the apache user and changing the permissions to 755 solved the problem.
Looking at the checkConfigSource() function in Config.class.php led me to believe that if the problem was with accessing the configuration file then I would have received the error 'Existing configuration file (%s) is not readable.' instead of Call to undefined function __() Does anyone know why that wasn't the case?
This was a pretty basic problem/solution, but unless someone suggests otherwise I think I'll leave it up since this exact problem/solution isn't addressed in other discussions of the Fatal error: Call to undefined function __() in /usr/share/phpMyAdmin/libraries/core.lib.php error when trying to start phpMyAdmin after installation.
