Fatal error when posting an article...

[Jaxel]

I keep getting the following error when I post an article...

Fatal error: Cannot redeclare handle_bbcode_video() (previously declared in /home/eightway/public_html/includes/class_bbcode.php(2463) : eval()'d code:24) in /home/eightway/public_html/vault/special_class_bbcode.php(2961) : eval()'d code on line 53

This error only shows up on wiki forums. If I disable ALL plugin based BB codes (lots of mods use these), then I can start posting/editing articles. For some reason Vault Wiki is polling the "bbcode_fetch_tags" plugin more than once... this is a bug that I'm amazed hasn't been discovered yet.

It's not a bug with VaultWiki. It's a bug in the video bbcode because it doesn't create the function in a require_once situation. It creates it within another function, when the entire purpose of a function is to be able to use it more than once.

Every function in vBulletin is called from a separate file using require_once. While plugin developers should be using the same method, some do in fact define functions inside other functions. But doing so creates potential for the issue you are experiencing. In this case, the plugin should also be checking function_exists:

if (function_exists('function_name'))
{
	function function_name()
	{
		...
	}
}
