We are changing our mywikis.com HTTPS certificate which expires on September 12, 2014 at 11pm CDT. We are changing it two weeks ahead of expiry to ensure that our secure website does not encounter any issues. Expect temporary issues with the secure HTTPS website and certain features of ClearCloud, which do not work on HTTP. In addition, we are switching our certificate authority from StartSSL to DreamHost by Comodo CA.
If you have any questions please feel free to ask us on Twitter, Skype, or our TSS (support.mywikis.com).
