Check your cache file for errors that are being created by this.

You could also try using the sample modded file that is enclosed.
It needs to be renamed.
If it works then you have added the code incorrectly to your version.
I uploaded the sample tpl_product_info_display file and it works now. It means that something was incorrectly with the code embedded in my original file. Now I'm going to adapt sample file to my needs.

Many thanks to gilby and DrByte for great effort to help me.
