Our investigations into the issues surrounding potential information leakage in the new version of EVElopedia are ongoing since early this morning. We have identified the core issue and are working on the appropriate fixes. It was related to some of the customization done within the MediaWiki software to support our Single Sign On (SSO) and not an issue in any way related to the SSO itself. Due to the sensitive nature of these things, and to ensure our engineers are given the time needed to resolve and verify this with due diligence, we will be keeping the new version offline until early next week.
In the meantime, and in order to avoid further interruption of your access to the useful information on the EVElopedia, we are reverting back to the previous version. This version is independent of the changes that were deployed yesterday, so there is no cause for concern that information could still be leaked. However, the website will be locked for editing articles until we redeploy the new version next week; you will be able to read all pages, but you will not be able to edit content on any page.
Please accept our sincerest apologies for any inconvenience caused by this.
