question about captchas

[JWalker]

Hi,

I have a question, it is not important, just I wonder what has happened.

The capchas do not appear in my daily used blog in the comment form while in the fresh clean installation appear. Small boxes appear with "CAPTCHA" string in it. Something prevents the browser to display the pictures of letters/digits, and it display the alternate text (alt="CAPTCHA"). I am using Apache rewriting (mod_rewrite) but not from very beginning of the blog usage... may be some other plugin interferes ? Fresh s9y installation from nightly build has no such problem, the captchas appear. Again, this question is not important for me, because I do not use comments just wondering why is this.

This can happen if any of your files outputs characters (empty linebreaks) before the plugin is executed.

Use WGET to get the image URL of the captcha, you might see those empty lines in that output then. This is what's preventing the browser to correctly render...
