wp-admin shows blank page, how to fix it?

Question

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-admin it 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.

Answer 1

[6] was spot on. I had the same problem ie a blank screen where wp-admin should have been Renaming plugins to pluginss let me get back in.

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.

It seems that it is very important to have an off-line backup The easy way to copy of the files is Filezilla (freeware)

You need a wordpress plugin for database backup - ie to back up all your pages and posts. But the pros will tell you that you need to get a

Answer 2

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 plugins folder 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 plugins folder, all plugins automatically has been disabled.

As I was inside the /wp-admin dashboard, 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.

Now is 100% fine.

Go to your functions.php page and delete any spaces immediately above or below your PHP tags.

Answer 4

In my case, wp-admin/post.php blank screen was fixed by removing the " ?> " at the end of my function.php in my child theme. I don't know how the end tag ended in there, but removing it solved my problems.

Answer 5

I have experienced the same problem as well. The reason was, that the functions.php was configured wrongly.

I did the following to solve the problem:

• In my child theme, I backed up all my files
• Then I deleted all of them leaving only the style.css page.
• I could then log in.

On reloading my functions.php I found it was the culprit. I rewrote the php and it was fine.

Answer 6

I had this problem (not showing /wp-admin/), when I moved my site to new host. i solve this problem by: 1. Re mane activated theme's folder 2. Install that them again and active it 3. copy and re place some customized file like .css .js from backup

Now problem solved.
