What would cause WordPress admin screen to be blan

So I've read through all the similar questions and can't find a solution here. Basically the user-facing site looks fine and is functioning properly. The WP Admin, however, shows only the left navigation menu... and nothing more.

I've tried all the basic solutions -- removing themes, removing plugins, turning on error reporting, and all that I get is a few typical warnings.

The admin was working fine a week or two ago - and I haven't been in it since. Also, it's a couple of versions old - but he original designer of this site warned NOT to upgrade WordPress or it would break the code.

So I thought I'd post the page source here to see if anyone may have a suggestion as to where to look from here. NOTE, this is the WPADMIN page source, not the the source from the website.

Here's a screenshot of what I'm seeing.

Here is what I get when I login to the WP ADMIN:

I noticed that the help sidebar is where it ends. Yet that doesn't give me anywhere specific to look.

Any help would be appreciated.

Thanks...

回答1:

Ok.. found it.

This was the offending code, and it was in wp-admin\includes\screen.php on line 706:

<?php echo self::$this->_help_sidebar; ?>

It should be:

<?php echo $this->_help_sidebar; ?>

Have no idea why this suddenly decided to go bad. And frankly I'm not sure I'll ever find out.

But wanted to help others if possible.

Take care everyone.. and thanks...

回答2:

FYI, I had the exact same problem, and this solution worked for me. ie: change:

echo self::$this->_help_sidebar;

echo $this->_help_sidebar;

回答3:

Indeed this worked for me too, changing to

<?php echo $this->_help_sidebar; ?>

I believe it is a matter of the php version we use
