Error

Hello

I installed Joomla and installed a template for it. But then it gives me this error

Quote:

Notice: Use of undefined constant T3_PATH - assumed 'T3_PATH' in C:\xampp\htdocs\test\templates\ja_playmag\html\com _content\featured\default.php on line 13 Notice: Use of undefined constant T3_TEMPLATE_PATH - assumed 'T3_TEMPLATE_PATH' in C:\xampp\htdocs\test\templates\ja_playmag\html\com _content\featured\default.php on line 25 Fatal error: Class 'PlaymagHelper' not found in C:\xampp\htdocs\test\templates\ja_playmag\html\com _content\featured\default.php on line 26

Any help?
