The reports are not so widespread to indicate a complete malfunction - but neither can we dismiss the problem, as being unique to one browser, one template type, or one particular update pattern.
It's likely that we are looking at a number of problems, aggregated and compounded, into one common symptom.
I cannot Save changes in Template Designer.With a problem report like this, some examining of the details may be appropriate.
The Template Designer wizard, which is a component in the Blogger Dashboard, is a complex and sophisticated collection of menus and utilities, which runs on the blog owners computers.
Like most Blogger code, the Template Designer is subject to the effects of other programs, and various security settings - which may be installed or set on each individual computer, with or without the understanding of the blog owner and / or computer owner. In some cases, the blog owner and computer owner may be different people.
If you are seeing a problem with the Template Designer, when trying to update the layout on your blog, there are several tests which you can make, which may help to isolate the problem.
- Try making the same updates, using another computer.
- Try making the same updates, using another browser on your current computer.
- Try setting up a new blog, with the same template, and make the same updates to the new blog.
Right now, I'm suspecting any of five possible causes of the problems, as currently reported.
- Changes made by Blogger Engineering, to support new browser versions and browser updates, and to provide new template features.
- Changes inherent in new browser versions, made by the browser vendors.
- Third party browser add-ons, installed by the owners of the various computers.
- Security settings, inherent in new browser versions and third party add-ons.
- The cumulative effects of various template tweaks, both made using "Edit HTML" and the Template Designer itself.
Recently, Blogger Support acknowledged the problem, in part.
Some users have reported that the Apply to Blog button in the Template Designer is non-functional for some Dynamic View templates.We also have a Rollup Discussion, in Blogger Help Forum: Something Is Broken, where individual details are being provided by various blog owners.
Right now, we're starting to suspect that some "problems" are actually caused by the blog owners, who are simply not aware that not all changes made, using the Template Designer (or the Layout or Template "Edit HTML" wizards), are designed to update all templates used in viewing our blogs.
