Jaben, I have the same problem, as wamprat:
Hi, I have been trying to follow the above instructions. (I am a noob to umbraco and YAF, and I am just putting this together for a POC).
When I try to go to the YAF install I get an about
Invalid language file C:\Inetpub\umbraco\languages\english.xml
Line 61: TimeZones.DataSource = YafStaticData.TimeZones( "english.xml" );
It would appear YAF is trying to look in the umbraco folder for this file when it should be looking in the YAF subfolder i.e. \umbraco\YAF\languages\.
I believe the file it is failing on is default.aspx.cs TimeZones.DataSource = YafStaticData.TimeZones( "english.xml" );
I could try and manually edit the cs file to look in the correct folder but no one else seems to of had these issues, so I am unsure this is the correct thing to do.
Thanks.
