My site was hacked and the useragent is sending googlebot the incorrect page. It looks like it is reading it the wrong language as a result of the extra code:
dir="ltr" lang="ja" xml:lang="ja"> <head> <meta http-equiv="Content-Type" http-equiv="content-type" content="text/html; charset=UTF-8" />
I can't find where the code is in the files. It is a mediawiki site. How do I fix this?
