Fatal Error WordPress 3.3.1

Fatal error: Call to undefined function wp_get_current_user() in /home/username/public_html/mysite.com/wp-includes/capabilities.php on line 1187

Getting this on WordPress 3.3.1

How can I fix this?

Thanks
Robert

Hello Robert,

Where do you find this error?

Right after plugin activation when trying to load my main site.. I patched capabilities.php with this at the top to prevent error..

include_once(ABSPATH . ‘wp-includes/pluggable.php’);

I found this while searching but not sure if this is the proper fix but it does seems to work.

Well that error simply means that WordPress was not loading that for some reason.

But since you’re telling it to load that file it now loads correctly.

Glad you were able to solve your problem Robert. :)

Well the truth is I have no idea if this is correct or not because I am not a php programmer or anything I just found this code in google while searching similar wordpress issues. It would be nice to know why this happened with s2member or is this strictly a wordpress issue that has not been patched? It’s just that I have not had it happen with any other plugins and I have many.. I guess it is because of the function call.. maybe s2member is the only plugin I have installed that calls this function and that is what triggered it..

I have a funny feeling that the contact form 7 plugin is what caused it..

Hello Robert,

Why do you have that hunch? Did you recently uninstalled it and the error went away? Have you tried de-activating it to see if that is the problem?

It was in fact after I installed the plugin but I had other plugins also active I just had a feeling that was the one for some reason.. I think I saw something about it when I googled for the issue..

OK Robert,

Thanks for the info, and now we know. ;)

I’ve identified that the plugin “SimpleModal Login” also causes this exact conflict when used with s2Member on WordPress 3.5.1.
