Log In Error

Try manually resetting your plugins (no Dashboard access required). If that resolves the issue, reactivate each one individually until you find the cause.

If that does not resolve the issue, access your server via SFTP or FTP, or a file manager in your hosting account’s control panel (consult your hosting provider’s documentation for specifics on these), navigate to /wp-content/themes/ and rename the directory of your currently active theme. This will force the default theme to activate and hopefully rule-out a theme-specific issue (theme functions can interfere like plugins).

Thanks James.

I already did the manual resetting of the plugins, will try your second option right now (though I already try to rename the themes folders name yesterday.)

I’am already worried that I might not be able to edit the website forever. (Its a company website by the way)

Hope you’ll stick around and let’s see if we could fix this issue.

UPDATE:

Warning: fopen(/dev/urandom) [function.fopen]: failed to open stream: Operation not supported in /wp-includes/random_compat/random_bytes_dev_urandom.php on line 58

Nothing happens when I change the /wp-content/themes/ active themes directory.

Our website is working fine by the way.. I just couldn’t really log in to the admin.

The tricky problem is that it could either be /wp-includes/random_compat/random_bytes_dev_urandom.php or something running *through* that file.

So, since you’ve ruled out the file itself, by replacing it, and the plugins and themes, by disabling them, it’s time for everything else.

Try downloading WordPress again, access your server via SFTP or FTP, or a file manager in your hosting account’s control panel (consult your hosting provider’s documentation for specifics on these), and delete then replace your copies of everything on the server except the wp-config.php file and the /wp-content/ directory with fresh copies from the download. This will effectively replace all of your core files without damaging your content and settings.

Some uploaders tend to be unreliable when overwriting files, so don’t forget to delete the original files before replacing them.

Hi James,

I am on that process right now, may I just ask when you say everything (except the 2 mentioned) are these files gonna be replaced too?

wp-active.php
wp-blog-header.php
wp-commenth-post.php
wp-config-sample.php
wp-cron.php
wp-links-opml.php
wp-load.php
wp-login.php
wp-mail.php
wp-settings.php
wp-signup.php
wp-trackback.php
xmlrpc.php

Thank you!

Yes, those too.

UPDATE:

I replace both wp-includes and wp-admin… plus the other files.

I still got the same error.

what the … is happening

Hm, can you contact your hosting provider’s support and ask them to make sure that fopen is supported on your server?

Hi James,

I just had a reply from our hosting provider, they do not support fopen… is there anything I could do to atleast fixed the website so I could access to the admin?

UPDATE:

I downgraded the version of the wordpress to 4.3.16, it turns out that our web hosting provider (which is yahoo business) doesn’t support the ‘random compat’ folder in the wp-includes folder.

I called their customer service and they told me they only support up to 4.6, but still when I did that it didn’t work.
