This error message is basically saying that MailPoet isn’t installed on your website. * Anyway, this plugin (add-on) you are using is not currently updated in a while, so there might be some issues with it. * Thread Starter [WendyG-Designs](https://wordpress.org/support/users/wendyg-designs/) * (@wendyg-designs) * [10 years, 11 months ago](https://wordpress.org/support/topic/getting-error-message-since-43-update/#post-6516822) * yes i have the mail poet wp-ecommerce addon installed i also tried installing just the mailpoet plugin but that just caused a white screen of death so had to remove it. * It appears the problem is a code error relating to the call on the lists it’s looking for a class wysija and not finding it * [Thomas Blomberg](https://wordpress.org/support/users/thomasdk81/) * (@thomasdk81) * [10 years, 11 months ago](https://wordpress.org/support/topic/getting-error-message-since-43-update/#post-6516847) * [@wendyg](https://wordpress.org/support/users/wendyg/): Mailpoet must be installed,“ mailpoet-wp-e-commerce-add-on” is an addon, only works if Mailpoet is installed. * Thread Starter [WendyG-Designs](https://wordpress.org/support/users/wendyg-designs/) * (@wendyg-designs) * [10 years, 11 months ago](https://wordpress.org/support/topic/getting-error-message-since-43-update/#post-6516850) * as i said the mailpoet plugin causes the white screen of death no admin area nothing we had it working then wordpress did an update to 4.3 and everything stopped dead i had to remove the mailpoet plugin in order to get the site working again however mailpoet provides a vital link with our sites customers. * Thread Starter [WendyG-Designs](https://wordpress.org/support/users/wendyg-designs/) * (@wendyg-designs) * [10 years, 11 months ago](https://wordpress.org/support/topic/getting-error-message-since-43-update/#post-6516852) * ok i updated the memory limit as specified in the help files i now get the following “ Plugin could not be activated because it triggered a fatal error.” “Fatal error: Call to a member function getValue() on a non-object in /home/wendygde/public_html/ wp-content/plugins/-wysija-newsletters/core/base.php on line 1487” * Now what do i do * Thread Starter [WendyG-Designs](https://wordpress.org/support/users/wendyg-designs/) * (@wendyg-designs) * [10 years, 11 months ago](https://wordpress.org/support/topic/getting-error-message-since-43-update/#post-6516853) * sorted it have it now working * [ikookmaar](https://wordpress.org/support/users/ikookmaar/) * (@ikookmaar) * [10 years, 11 months ago](https://wordpress.org/support/topic/getting-error-message-since-43-update/#post-6516867) * What did you exactly do to sort it out?
