I have installed it from magento connect, and now in my back-end it displayed as it. Please somebody help me how to fix it. I gues it causing by i was put the compliation mode in on. Thank you

  • put the compilation mode 'off'. Then refresh the cache and logout and login back. Still the error is there, check whether the installed module contains a helper class as Data.php. If exists check the class name is correct.

Please Check in your Module like

If your module in Local folder then

app/code/local/Altima/Lookbook/Helper/Data.php file Available or not if not then please create the file as below code.

  class Altima_Lookbook_Helper_Data extends Mage_Core_Helper_Abstract

Now refresh your cache and test it
