wp-admin shows blank page, how to fix it?
提问by Anandkumar Mehta
I am working with WordPress 3.5.8. Yesterday I made some changes into it to a friend. I don't know what happened, but after some time when I try to log in at wp-admin side and execute URL www.mysite.com/wp-adminit shows me a blank page. How do I solve this? I have searched over the internet and blogs. I found it could be related to hosting problems or brute force-attack, but I don't think that that's what happened to my site.
我正在使用 WordPress 3.5.8。昨天我给朋友做了一些修改。我不知道发生了什么，但是一段时间后，当我尝试在 wp-admin 端登录并执行 URL 时，www.mysite.com/wp-admin它向我显示了一个空白页面。我该如何解决这个问题？我在互联网和博客上搜索过。我发现这可能与托管问题或蛮力攻击有关，但我认为这不是我的网站发生的情况。

After dozens of times trying to fix this problem reading forums and posts, reinstalling WordPress, removing white spaces, putting lines of code in wp-config.php, index.php, admin.php, I fixed the issue just by renaming the pluginsfolder to "pluginss"in FTP. So wordpress asked me to update the database. I updated and I could enter at /wp-admin. A plugin was causing some conflict, so when I rename the pluginsfolder, all plugins automatically has been disabled.
在阅读论坛和帖子、重新安装 WordPress、删除空格、将代码行放在 wp-config.php、index.php、admin.php 中数十次尝试解决此问题后，我仅通过将plugins文件夹重命名为"pluginss"在 FTP 中。所以wordpress让我更新数据库。我更新了，我可以在/wp-admin. 一个插件导致了一些冲突，所以当我重命名plugins文件夹时，所有插件都自动被禁用。
As I was inside the /wp-admindashboard, I could rename the "pluginss"folder to the regular name and start to activate all the plugins one by one and see what plugin was broken.
当我在/wp-admin仪表板中时，我可以将"pluginss"文件夹重命名为常规名称并开始一个一个激活所有插件，看看哪个插件坏了。
Now is 100% fine.
现在是 100% 罚款。

Go to your functions.phppage and delete any spaces immediately above or below your PHPtags.
转到您的functions.php页面并删除PHP标签正上方或下方的所有空格。

I faced the same problem and I tried many things such as trying to login through wp-login.php instead of /wp-admin and adding ob_start() in /wp-admin/index.php (if you hit the url /wp-admin it goes for /wp-admin). It showed login page but entering the username and password shows an error like "cookies are blocked due to unexpected output".
我遇到了同样的问题，我尝试了很多方法，例如尝试通过 wp-login.php 而不是 /wp-admin 登录，并在 /wp-admin/index.php 中添加 ob_start()（如果您点击 url /wp- admin 它用于 /wp-admin）。它显示登录页面，但输入用户名和密码显示错误，例如“由于意外输出，cookies 被阻止”。
I finally got the solution: it happens because the theme or plugins that you installed are not supported.
我终于得到了解决方案：这是因为您安装的主题或插件不受支持。
How to check and fix:
如何检查和修复：
Rename the plugin folder name and theme folder name.If opening /wp-admin and entering a valid username and password the dashboard is shown, then it worked.
Revert the folder name of plugin and theme, then activate the themes and plugins one by one, cross-checking with /wp-admin. You will find out the unsupported plugin or theme.
重命名插件文件夹名称和主题文件夹名称。如果打开 /wp-admin 并输入有效的用户名和密码，仪表板就会显示出来，那么它就可以工作了。
恢复插件和主题的文件夹名称，然后将主题和插件一一激活，与/wp-admin交叉检查。您会发现不受支持的插件或主题。

All your problem is solved right now just follow this instruction:
您的所有问题现在都已解决，只需按照以下说明操作：
- go to your themes then de activate your current theme, just put "x" in the the first letter of your theme name.
- 转到您的主题然后取消激活您当前的主题，只需在主题名称的第一个字母中输入“x”即可。
for example this is your theme folder name: "mytheme" just put "x" in the first letter like this "xmytheme" tho di activate.
例如，这是您的主题文件夹名称：“mytheme”只需将“x”放在像“xmytheme”这样的第一个字母中即可激活。
Then after that go back to your wp-admin panel then BOOM! wp-admin accessable.
When you access your wp-admin panel or you are on your dashboard, again activate your theme again, but before that. REMOVE THE "X" letter you putted in your theme name. example: "xmytheme" just remove "x", output like this: "mytheme"
- then activate it in your dashboard.
然后回到您的 wp-admin 面板，然后 BOOM！wp-admin 可访问。
当您访问 wp-admin 面板或在仪表板上时，再次激活您的主题，但在此之前。删除您放在主题名称中的“X”字母。示例：“xmytheme”只需删除“x”，输出如下：“mytheme”
- 然后在您的仪表板中激活它。
hope this help!.
希望这有帮助！。

I also had a blank screen for my blog. The solution was to copy up a backup copy of wp-config,php somehow the 'live' wp-config.php had been replaced with a file size of zero.
我的博客也有一个空白屏幕。解决方案是复制 wp-config,php 的备份副本，以某种方式将“实时” wp-config.php 替换为文件大小为零。
In my case I had the same problem. Helped remove the wp-config.php file. Wordpress created new wp-config.php file and wp-admin is working flawlessly now. Rename plugins, themes folder does not help.
就我而言，我遇到了同样的问题。帮助删除 wp-config.php 文件。Wordpress 创建了新的 wp-config.php 文件，并且 wp-admin 现在可以完美运行。重命名插件，主题文件夹没有帮助。

It seems that it is very important to have an off-line backup The easy way to copy of the files is Filezilla (freeware)
看来离线备份很重要复制文件的简单方法是Filezilla（免费软件）

It might be because of a few reasons:
可能是因为以下几个原因：
- Problems in your web host.
- Theme related errors(You can change it by renaming theme folder).
- Plugin related errors(You can change it by renaming plugin folder).
- An Empty line in your wp-config file.
Code errors that can be seen by enabling Debug mode.
"define('WP_DEBUG', true); // Enable Debug logging to the /wp-content/debug.log file define( 'WP_DEBUG_LOG', true );
// Disable display of errors and warnings define( 'WP_DEBUG_DISPLAY', false ); @ini_set( 'display_errors', 0 );"
- Remove blank space in functions.php or you can also remove the last "?>"
- 您的虚拟主机中的问题。
- 主题相关错误（您可以通过重命名主题文件夹来更改它）。
- 插件相关错误（您可以通过重命名插件文件夹来更改它）。
- wp-config 文件中的空行。
通过启用调试模式可以看到的代码错误。
"define('WP_DEBUG', true); // 启用调试日志记录到 /wp-content/debug.log 文件中 define('WP_DEBUG_LOG', true);
// 禁止显示错误和警告 define( 'WP_DEBUG_DISPLAY', false ); @ini_set('display_errors', 0);"
- 删除functions.php中的空格或者您也可以删除最后一个“？>”
