this is another bx error code that has been associated with trying to add a template to one's blog.

The most common solution is that the template that you are trying to add has either missing or corrupt coding in it and that is why it is not being accepted by Blogger.com.

It may become necessary for you to have to go through the entire template to see if you can spot the missing and / or corrupted coding and correct it.

You can also view some different blog templates that I have successfully been able to upload and use in my Different Blog Layouts Blog

this is another bx error code that has been associated with trying to edit the html of one's template.

You have to understand that the most probable reason why the edits you have made to your blog's template are not being accept is because you may have corrupted the coding in some way when you edited it.

Unfortunately the only solution seems to be that you will have to go back to your blog's original template (hopefully you have a back-up copy of your blog template) and re-load that back in so that your blog will be back online.

In the meantime you will have to go over the editions you made to see where you could have likely corrupted the coding and try to remedy it so that you can add the new additions to your blog template (and have those editions be accepted!)
