I just started getting this. Didn't do anything I know of. I have verified this file is there and works. Looked in side of it. Line 1, position 1 looks like this in the document <browsers> <browser id="Safari2" parentID="Safari1Plus"> <controlAdapters> <adapter controlType="System.Web.UI.WebControls.Menu" adapterType="" /> What am I missing here?

Idea of what could be the issues was only found here. http://forums.asp.net/thread/1270047.aspx In doing some editting on the intranet site which is WSS v3 I openned a file called web.config from the c:\inetpub\wwwroot\wss\virutaldirectories\80 ok so no big deal didn't edit the file or change anything. I openned the file with SharePoint Designer after I did this I remembered I needed to work in these files in Virtual web designer and not sharepoint designer ok my bad didn't save anything seems stupid but I didn't give it a thought. Just openning the file seems to be enough to have the system create a sub folder called _vti_cnf or something like that. In trouble shoot this error I openned a few files and it created this folder and made a copy of each folder I openned and put it in a sub folder with the _vti_cnf name I found 6 of these folders all new. I guess this file is not a true xml file and made the whole site crash for 2 hours. I deleted these directories and everything worked right away.

This has happened to me just by adding a new ISAPI filter to the sharepoint website and modifying the web.config file. All the sudden I start getting this parse error.. and of course in a production enviroment.. First I thought about shooting myself, but finally I googled out your solution.. it worked.. but I'm madly mad!! WTF bug in a Enterpise version of a software that cost this much money?! still can't believe it.. thank you again for your solution..

Thanks a lot. it worked for me too.S.Navid.Rhttp://sharepoint4u.wordpress.com

thx a lot ! worked for me too !

Thx so much... It worked!

tks a lot.. just rename de directory "App_Browsers" to another.. it Worked !!!

Yep - this happened to me too - and I can't say that his remarks were "WAY" off limits - thanks jbenisek for taking the time to post the answer Mike - could you explain why SPD takes liberiteis to create files that will screw up the whole site like that? It would be nice if we could use one tool for editing things instead of having to walk on eggshells and not open certain files in SPD

Hi All, I am also getting same issue but unable to find the folder or file name _vti_cnf as i am working on SP2010 After lots of struggle found the solution: When user copy the compact.browser in App_Browsers . the sharepoint automatically increment count the tag with the number of files Just delete all the file and put only one compact.browser file.
