Your VW_DEFAULT_SCRIPT is wiki_index.php. This is not supposed to create an infinite loop, but looks like it is in your case. Set VW_DEFAULT_SCRIPT to forum.php instead if you're on vB4 or vbseo.php if you use vbseo.

It's a fresh install, it also seemed to screw up my website now to where no image shows, it's weird, and the website is running slower than what it was before i installed vaultwiki. I am using Dragonbyte SEO with it, and i am pretty confident i done it right.

If you are using Dragonbyte SEO, it is possible the instructions are different than for a vBSEO install. Since the rewrite rules were the same we thought the install instructions were the same, but it is possible additional configuration needs to be done. If you cannot work it out, I will add a free install service to your account so we can set it up for you.

I filled it out, if you need any information or w/e, just pm me or leave a comment here. Take as much time as you need also, i am in no rush or anything and hopefully it's a good test site for you to resolve this conflict for future use.

Fixed. Unlike vBSEO, dbSEO sends the request back to the calling script if it doesn't know how to handle it. Since VaultWiki hands the request to dbSEO, when it can't handle it, we can find ourselves in an infinite loop.

wiki_index.php has been modified for the next release. If this particular loop is stepped into, VaultWiki will simply output the wiki index page.

Ideally, though, dbSEO should also be updated so that it doesn't hand a request back to a file that's above it in the get_included_files stack. A proper fix by the dbSEO devs would be similar to the following. In dbseo.php, find:

Code:

		if (substr($fileType[1], 0, 2) == 'ph' OR $fileType[1] == 'php')
		{
			// This was a PHP file
			require(getcwd() . '/' . $_fileName);
		}
		else
		{
			// Any other kind of file
			echo file_get_contents(getcwd() . '/' . $_fileName);
		}

Replace with:

Code:

		$inc = get_included_files();
		$_filePath = realpath(getcwd() . '/' . $_fileName);

		if (!in_array($_filePath, $inc) AND file_exists($_filePath))
		{
			if (substr($fileType[1], 0, 2) == 'ph' OR $fileType[1] == 'php')
			{
				// This was a PHP file
				require(getcwd() . '/' . $_fileName);
			}
			else
			{
				// Any other kind of file
				echo file_get_contents(getcwd() . '/' . $_fileName);
			}
		}
		else
		{
			DBSEO::handle404('', true);
		}

They have updated dbseo to include your fix, so this issue should not be ran into again.
