When I visit the download link at http://www.delegacionprovincial.com/mediawiki/index.php?title=Gestion_Online:NagVisExtensionDownload I'm getting a 404 now.
UPDATE FOR NAGVIS 1.8
I hope you won't mind but I modified your extension to work with NagVis 1.8 and the current version of Mediawiki 1.24.1
New version which includes 1.7 and 1.8 branches
Thanks for your work and interest in Nagvis Mediawiki extension.
- That's great! It's works beautifully! Thank you very much :) --Ed 20:32, 24 March 2015 (UTC)
