I guess I don't know what you mean by examples because I see examples for all your custom bbcodes (Example Usage and Example Output), just as there are examples for the default ones. Example Usage will be what you write in the Example box in the manager and Example Output is what you would see if your Example Usage was pasted in a post. OK, I think what you are saying is your Example Output isn't being parsed correctly. Yours stops working after the Image Code ([url]) - right before the code tags ([code]).
Have you tried disabling your plugins to see if that is causing the problem?
Note: To temporarily disable the plugin system, edit config.php and add this line right under <?php
PHP Code:
define('DISABLE_HOOKS', true);
Don't forget that for vbseo, disabling the modification means to also get rid of anything extra you added to your htaccess file.
