Post error - valid callback to wp-includes/plugin.php on line 486
on: Jan 23 2012, 02:16 PM

Hi, all

I've been using mingle with the default skin without any problems, but when I installed the DarkPress skin (and other skins create this problem, too, I don't recall which ones offhand.) and I update the wpf-class.php file, I get the following php error..

Warning: call_user_func_array() [function.call-user-func-array]: First argument is expected to be a valid callback, 'mingleforum::before_go' was given in /home/nwufo907/public_html/wp-includes/plugin.php on line 486

I've disabled a few suspect plugins with no change, reloaded the files, etc. I'm running wordpress 3.3.1 with mingle 1.0.33

Any ideas?

TIA

An update..

I disabled all plugings except Mingle and still get the above error, so it's not probably not a plugin interaction. I also reverted back to the factory original wpf-class.php file. The error went away and the forum seems functional. There are a few layout burps here and there, these may be side effects, no biggie.

I too have these issues, only with Dark Press. Just registered an account here to try and fix them, because it's the only skin for dark sites that actually looks good.

Also, the images for like: Forum Home, My Profile, and Search etc. don't show up. This happens with both wpf class files, and even affects other images on the forum page. I believe its the skin's fault, and it may not be updated to the newest version of MF.

Any support on fixing this would be appreciated.

First post on the forum and I hope it helps someone out.

I figured out a simple work around for the time being by examining the original wdf-class.php file against new ones. This is what I came up with. You need to edit the new wdf-class.php file (new themes), not the original.

This:

		function before_go()
	{
		$this->setup_links();
	}

Needs to be added before:

	function go() {
		ob_start();
		$start_time = microtime(true);
		global $user_ID;
		get_currentuserinfo();

And after the:

}

By doing this, the error message vanished on my end. Since I'm not really a coder, I can't offer any help further than this since I just tinkered and found this solution for myself.

Hmm disregard that for now, it threw more errors out when I made that change. I'll keep trying though.
