Php Mediawiki：对不起！此站点遇到技术困难。无法访问数据库

我相信这实际上不是连接问题，因为我可以看到“title-invalid-e”，并且我可以使用在LocalSettings.php文件中找到的相同凭据进行连接

任何帮助都将不胜感激

对不起！此站点遇到技术困难

尝试等待几分钟并重新加载

谢谢你看这个问题。如果我能更新这个问题的话，那么在投票结束时获得一些反馈会很有帮助，我很乐意这样做。为什么你认为它会像你一样使用LocalSettings.php中的凭据？DB设置存储在这里。不是吗？很可能这实际上是一个数据库访问问题，wiki无法使用其凭据登录数据库。它试图从本地化缓存加载一条关于无效标题的消息，该消息返回到数据库（

LCStoreDB.php

），然后失败
