As usual when applying a non default value CB collapses in great fashion ...
You do not need to include such a negative reply in every post of yours. Being so quick to be negative is detrimental to the community and the morale of those involved. Please stop being so quick to judge. We're here to help; that's the purpose of support. Your issue has nothing to do with CB doing anything wrong. Your issue is just standard PHP (you have 2 classes with the same name).
I made a copy of the default profile template, installed it via the plugins and set it in the config. Now accessing a users profile gives the ultimate failure.
Copying and installing the default does not work as you end up with duplicate classes, plugin elements, and plugin files. The XML filename as well as the name and element in the XML file must be changed. Once done the class names need to be changed in the PHP file. So you'd have the following for example.
XML Filename: example.xml
XML Name: <name>Example</name>
XML Element: <filename plugin="example">example.php</filename>
PHP Filename: example.php
PHP Classname: class CBProfileView_html_example extends cbProfileView
The PHP class names all need to be adjusted in your new example.php as exampled above.
I couldn't find any tutorial on google for doing my own template so I guess there is none.
Nick has provided a template override tutorial. Video and example installable template plugin included. I do not recommend using a template that is not override usage as your PHP file could quickly go out of date with new releases of CB. Using the override template you can override the default templates CSS with your own styling, but still allow everything to inherit correctly so you don't risk your template going out of date and missing fixes/features.

but it is not that easy when that thing explodes after every turn, but I try to keep it to myself ...
