Thread:Extension talk:MSSQLBackCompat/blank pages with MediaWiki 1.22 - getSoftwareLink()

I got blank pages using ExternalData and MSSQLBackCompat with Mediawiki 1.22.

I found that the problem was the getSoftwareLink method defined in DatabaseMssqlOld.php; so I removed the static keyword and the extension began to work.

I think the problem come from this: https://gerrit.wikimedia.org/r/#/c/63824/

Hope this helps.
