I have an "index.html" (or .php - it makes no difference) file in the root / of my hosting space. That "index.html" file has this line of code in it:

When I try to access my domain name, I get a customized internal server error message "Internal server error, please contact ..". If I remove that line of code, it works.

If however, I create a folder called "test", put the "index.html" file inside it and access the file as "mydomain.com/test" everything works fine.

Any ideas? (i will try a js replacement however, this goes to the general point, of why does the error pop up?)

This sounds like an issue that is specific to your hosting provider. The likely explanation is that they have a check in place to look for malware on the home page of your site. Base64 encoded JavaScript is often used to obfuscate JavaScript inserted by a hack. Their malware scanner triggers when it detects any Base64 encoded data.

To resolve the issue you would need to contact your web host. They may be able to disable this check for your site.

Here's a screenshot of the result in Firefox (v38.0.1), showing your icon working from base64 encoded inline data both as a favicon in the browser tab and also as a static image within the body section of the web page.

As mentioned before in a comment I've tried this file with 3 different hosting environments/providers with consistent results and have been unable to reproduce the issue you had described where an Internal Server Error is generated by Apache.

Tested/known working configurations:

2.6.18-164.el5, Apache v2.2.3, PHP v5.3.4-dev
3.2.61-grsec-modsign, Apache v2.2.29, PHP v5.4.37
2.6.18-471.3.1.el5.lve0.8.72, Apache v2.4.12, PHP v5.4.40
