My readers can't leave me comments!and when I diagnose the problem
The blog uses an inline ("Embedded below post") comment form, with CAPTCHA ("word puzzle") verification. Your readers need to check their cookie and script filters, starting with "third party cookies".the response will frequently be
No way! My readers can't handle that!
Blogger offers three comment form options, each with their good points, and their bad points.
- Full page
- Pop-up window
- Embedded below post
With the coming of the Google "One account" login, all login cookies created under "google.com", and accessed from a Blogger blog, are now vulnerable to "third party" cookie filters.
If your blogs readers are limited in their potential to deal with layered security issues, you'll want to consider the security requirements of the three options, in choosing how to have your readers publish their comments.
Many years ago, Windows level security ("Allow everything by default, block only when necessary") was normal in our browsers, and on our computers. As Internet based security risks increased, security accessories and settings using Unix level security ("Block everything by default, allow only when necessary") became more normal.
Comment forms in a full page are the easiest to allow, in general. Full page forms use a script that runs, in the browser, as "Blogger.com" - which used to be the same domain as the cookies were generated. This does not, any more, eliminate the need for "third party cookies", and for any security settings that would allow scripts, from BlogSpot or from your domain, to run in your readers browser. This is the best choice, all around.
Comment forms in a pop-up window may be blocked by various ad or script blockers. Pop-up windows use a script that runs, in the browser, as "Blogger.com" - which used to make them a good alternate choice for blogs published to BlogSpot. If your readers either
- do not use ad or script blockers
- can handle modifying the pop-up filter setting, to allow "Blogger.com"
Comment forms embedded below post use a script that runs, in the browser, as either "BlogSpot.com" (for blogs published to BlogSpot), or as your domain (for blogs published to a custom domain). Since the settings are, again, selected in "Blogger.com", this creates the need for "third party cookies" to be allowed - as well as scripts from "BlogSpot.com" or your domain.
I do not recommend allowing scripts from "BlogSpot.com". If your blog is published to BlogSpot, or if your readers have any problems with managing their layered security settings, I recommend that you avoid this choice.
Please note that third party cookies may still be necessary on many readers computers, for those readers that want to use the "Remember me" option when they login, for their preferred use of Stats, or for Template Designer.
