Stupid Templates - NEED help please

[The Markus]

I am Having trouble with a few hacks because it requires template modifications

In the latest hack I am installing from Erwin
https://vborg.vbsupport.ru/showthrea...d=1#post576943

I get an Error in my template..

But anyways,

1. How do I know whether I am using "postbit" or "legacy postbit"?
2. What is a template?
3. when someone says "Find this code" in a template and I locate it, its never on the same line. For instance if its a longer line of code, part of it will break off into the next line. So when I copy and paste the code I am supposed to add, it too breaks off into a new line.
4. Can someone tell me what this means? (I am inexperianced with PHP but I am learning):

Parse error: parse error, unexpected T_ENCAPSED_AND_WHITESPACE, expecting ']' in /home/covenan/public_html/forums/includes/adminfunctions_template.php(3055) : eval()'d code on line 213

Thank You kindly guys....
