  • check if all files for this module are on your live server (module declaration / config.xml etc). Try cleaning cache again. – bchatard Feb 13 '16 at 6:06

    Check also file permission – ProxiBlue Feb 13 '16 at 6:52
  • I cleaned cache Mutiple times. have done the file/folder permissions but problems remains the same. I copied the app folder as it as from local to live server and then copied layout file to app\design\adminhtml\default\default\layout\mymodule.xml and copied the last file to app\etc\modules\Mycompany_Mymodule.xml – nzafar Feb 13 '16 at 22:41

As long as you did not define your blocks type as Mycompany_Mymodule_Block_Adminhtml_Mymodule in your layout.xml the error Message is saying that your Module and also the layout updates do work basically.

Would still be helpful if you could post the xml where you add the block in the layout

For some reason the class cannot be loaded by the autoloader. This can be due to a typo in the Class Name, File Name, layout.xml or Directory.

another reason would be if you don't have the block directive in your config.xml under global.

  • app\etc\modules\Mycompany_Mymodule.xml <?xml version="1.0"?> <config> <modules> <Mycompany_Mymodule> <active>true</active> <codePool>local</codePool> </Mycompany_Mymodule> </modules> </config> – nzafar Feb 13 '16 at 22:43
  • layout file --- <?xml version="1.0"?> <layout version="0.1.0"> <mymodule_adminhtml_mymodule_index> <reference name="content"> <block type="mymodule/adminhtml_mymodule" name="mymodule" /> </reference> </mymodule_adminhtml_mymodule_index> </layout> – nzafar Feb 13 '16 at 22:43
  • I copied the working folder from local system to live server without editing anything so chance of typo are close to 0. – nzafar Feb 13 '16 at 22:46
  • in your etc/config.xml do you have the following part? (it's important so that magento can locate your block classes) github.com/bragento/magento-core/blob/1.9/app/code/core/Mage/… – David Verholen Feb 13 '16 at 22:51
  • yes.. please find below my config.xml (Thank you for your help ) <blocks> <mymodule> <class>Mycompany_Mymodule_Block</class> </mymodule> </blocks> <helpers> <mymodule> <class>Mycompany_Mymodule_Helper</class> </mymodule> </helpers> </global> – nzafar Feb 13 '16 at 23:07
