In preparation for the October 2016 release, when the Old e-Portfolio themes will be switched off, all blogs using those themes have been switched to the TwentyFourteen theme. No content is lost. The features of the theme which produced the profile has been lost. We recommend using the new e-portfolio plugin for creating e-Portfolios and profiles.
