Urgent help needed with PHP code in a wordpress post.

I'm in a real bad spot atm and need some serious help.

I was putting php code in posts in wordpress using a plugin: execPHP.

Everything was working fine all day. I don't know what changed, but now, no PHP code is converting. I've tried two plugins, execPHP and runPHP, both with the same results.

The entire post of that was written in the regular html (not WYSIWYG).
The posts contents are:

Learn how to correctly use a pushbot chart for late-stage tournament play.

<?php
global $userdata;
get_currentuserinfo();
$userid = $userdata->ID;

echo ('<a href="http://www.pokerjuke.com/buynew.php?subid='.urlencode($userid).'&item=pushbotguide"><span style="color: blue;"><span style="text-decoration: underline;">Pushbot Video Guide</span></span></a>');
?>

Code (markup):

The things I fiddled with that might have caused this issue:

I unchecked the "Use the visual editor when writing" box in the admin panel.

I changed roles of a user. I know you can set user permissions to who can run php code. The code was written by an admin with access.

That's about all I did. The only reasonable thing I think that could have caused this is disabling the visual editor. I have checked the box again and tried making new posts but I still get the same problem. Plus, I remember viewing pages after making that change and they were fine.

I don't remember editing anything at all in between when pages went from working to broken.

I'm very worried that my site is going to need a complete rebuild now. Can anyone think of anything that might save me from that?

Any help or ideas are much appreciated. I'm new to this stuff and completely lost

 

If are using this code on every post, put it directly in your theme page.

 

Fixed I wasn't using it on every page. I added an if statement to check which category the post was in and only add the code on those pages.

Thanks.
