You can solve this conflict by following go to this class file app/code/CLASSCODEPOOL/CRM4Ecommerce/CRMCore/Model/Rewrite/Core/Email/Template.php and change its extending class to


so your class would be like this

class CRM4Ecommerce_CRMCore_Model_Rewrite_Core_Email_Template extends Aschroder_SMTPPro_Model_Email{
    //your methods  .....
  • I did as you explained but now I get other messages!! SMTP Pro Self Test Results Detected overwrite conflict: CRM4Ecommerce_CRMCore_Model_Rewrite_Core_Email_Template Test email was sent successfully. Could not test default template validity. Exception message was: Invalid method CRM4Ecommerce_CRMCore_Model_Rewrite_Core_Email_Template::loadDefault(Array ( [0] => contacts_email_email_template [1] => en_US ) )... Please check that you have templates in place for your emails. These are in app/locale, or custom defined in System > Transaction Emails.

  • so your solution is to replace (Mage_Core_Model_Email_Template) with (Aschroder_SMTPPro_Model_Email) which I did but now I get the error message above.

  • you have to change your config.xml as well now you need to rewrite the SMTPpro extension model instead core email model Commented Sep 30, 2016 at 2:59
  • I don't think that I understood what you just said. Can you please explain? I'm new to this.

  • I just noticed when I edited the file you mentioned above and extended the class to Aschroder_SMTPPro_Model_Email all transactional emails stopped working even if I try to preview a transactional email template. I restored the files and everything went back to normal. Still can't figure out how to fix this issue. Both authors and their websites don't respond so far.
