Even with the difference between Blogger and BlogSpot - and the need for cookies to be created under one, and read under the other - explained, some people see cookies and scripts as an equal threat. This is where problems with various Blogger features start.
Your browser, such as Chrome, Firefox, Internet Explorer, and many others, is an application that you run on your computer. Your browser takes web pages, written in static HTML - and with Blogger, various extensions such as CSS, dynamic HTML, and XML - and displays those web pages on your computer.
Cookies and scripts both display affect website provided content.
In order to display the web pages on your computer, Blogger uses two rather controversial elements - cookies, and scripts. Cookies and scripts are similar.
- They both originate from a server, on the web.
- They are both filtered, in various layers of security, on our computers.
- They are both stored, in cache, on our computers.
- They are both cleared, from our computers, when necessary - sometimes causing various problems.
- They are both text files - not executable modules.
For all their similarities, they have one major difference - how they are treated by the browser.
- Cookies are data. You, a human, cannot necessarily "read" (visually interpret) the data - but they are still content that must be read, and interpreted, by a computer program. Cookies cannot contain malware - nor transmit malware - by themselves.
Too many computer owners believe that cookies and scripts are equally dangerous.
Unfortunately, too many people have decided that cookies and scripts are equally dangerous. Many browsers, and other components of righteous security policy, contain filters that prevent both cookies, and scripts, from being used when necessary.
Many Blogger blog owners, and readers, trust the default filter settings, and cause the problems with their various Blogger features.
- Template Designer.
To complicate matters, each new version of every security layer may have newly restrictive filter settings. And not every owner, of every computer, used to maintain and read Blogger blogs, is qualified to maintain the components of layered security, on an ongoing basis.
And that is why you have problems with your Blogger blogs.
- You can't login to Blogger, or stay logged in to access and maintain your blogs.
- You (or your readers) can't post comments to your blogs.
- You can't view Stats for our blogs - or can't view Stats with the desired detail.
- You can't customize your blogs, in Template Designer.
Every computer owner, not part of a corporation, maintains their own computer.
And many of these problems are caused, quite simply, with how each of us, individually, use our computers, in general. They are not unilaterally caused by Blogger - nor can they be, unilaterally, resolved by Blogger / Google.
The simplest diagnosis, of many problems, starts with checking / correcting browser cookie filters - and complementing that, by checking / correcting browser script filters.
