I installed NWiki by deleting Wiki from the modules page and from the mod directory. Then I unpacked the zip folder into my root moodle directory and all files seem to have been extracted fine. When I went to admin page all updates were successful. I checked lang/en and lang/en_utf8 and they both have wiki.php files. When I go into NWiki everything has the words brackets going on.
Can some help with what I may have done wrong or what is going on.
Thanks
I figured out my problem--when I unziped NWiki it did not overwrite the old Wiki.php lang files. So after I overwrote those with the files from .zip package it worked. I thought when I unzipped the process would overwrite existing files but I guess not or maybe it was a file ownership issue on my server?
