A while back, Google announced that they were shutting down Google Page Creator and offered users the option to upgrade to Google Sites. In the past, some custom template designers used Page Creator to host javascript, a file type that Google Sites does not support. Since a number of bloggers use templates that rely on files hosted on Page Creator, we realized that links to those files would break once the migration from Page Creator to Sites was complete.
Fret not! Rather than see our users' templates break, we built a tool to preserve these links and host the affected files. To find out if your blog is affected, login to your Blogger Dashboard. If we've detected that your blog template contains links to Google Page Creator, you will see the following warning:
If you see this warning, click Update and review to access the Blogger Template Fixer and correct the links on your blog. (Note: you may not notice any problems with your blog until Page Creator shuts down over the coming days). Visit our Help Center to learn more about fixing your template.
Also, if you have issues fixing your template, let us know at the Blogger Help Group.
