BX Error Code during uploading a new template

Many Blogger users have experienced Bx-error codes when attempting to upload a new template to their blogs when previously these templates had worked just fine.

I discovered the reason for this on the Blogger Help Group after reading this post from Gatsby, a Blogger Employee:

Recently we changed the way our template editor accepts certain third party code, so that it is now less tolerant of certain templates. We did this because we had seen a lot of data corruption due to 'bad templates,' and we are trying to stave off some of these issues pre-emptively.

Now we realize that this has caused some inconvenience to folks, so we are re-thinking our decision and will post an update on that shortly.

At the time of writing this post, I have not found any notification that this issue has been fixed, and many of my own custom templates do not work in their initial state (I'll explain the fix later in this article). Since there are so many bloggers complaining in the Blogger Help Group, I would imagine the Blogger Team will resolve this issue shortly.

However, in the meantime, many of us are stuck wondering what to do about our templates:

• Those wishing to upload a new template will at present need to fix their template in order to be able to use it.
• Those of us who design and distribute Blogger templates are facing complaints from our readers (and in some cases, from buyers of our premium themes). Should we "fix" all of these templates or wait for the Blogger team to resolve the template editor issue?

Personally I would prefer to wait a few more days for the Blogger Team to fix the issue (and hopefully provide some clarification of what is expected from third-party templates!). In the meantime, there is a method which we can use to fix the templates which initially receive a Bx-error code.
