Glow are planning a new release on Glow Blogs in July. This will consist of some improvements to the service, fixes and updates. More details soon.
As part of the release Glow will be removing some themes that are currently disabled. These include the old e-Portfolio themes and 4 Woo themes.
This will have an impact on some existing sites. Sites that are using these themes will switch to the TwentyFourteen theme. Glow suggest that it will be better to manually switch themes before the release.
e-Portfolios can be switched to another theme and updated to use the new e-portfolio plugin.
There is help for converting an old theme to a new one on the help blog:
Of the four Woo themes the only one with more than a very few sites, is Spectrum News.
There is a page on the help blog with notes on converting a Spectrum News site to using the TwentyFourteen theme:
If you have a blog or a child has an ePortfolio using the Spectrum News theme we would strongly suggest you change it to another theme before the end of term.
