Thread:Project:Support desk/Accidentally deleted .htaccess(?), now can't access wiki

My wiki is (or was) at http://www.ilaisu.org/wiki/Main_Page. Unrelated to the wiki, my wife added a directory at http://www.ilaisu.org/pv/, and attempted to password protect it using .htaccess and .htpasswd files. Whatever way she tried to do it did not work, and the entire domain was no longer accessible (putting in the username and password just gave an error). So she tried to fix it by deleting the whole directory and the files she added, and now although the domain is accessible and she says she did not delete anything out of the /w/ directory the wiki files are stored in, the wiki comes up 404. I'm guessing she deleted the .htaccess file for the wiki.

Although I configured the wiki myself, it was a long time ago, and even at the time I was not an expert, I was just following directions without really understanding them. Is there some kind of basic or default .htaccess file I can use to at least be able to access the wiki again, if not get back any configuration I may have done? Thanks.
