I have installed the WhatsApp module. It seems to be working fine on the frontend, but I keep on getting the following error message in my error log:

Undefined index: HTTP_ACCEPT in /home/..../public_html/catalog/view/theme/default/template/module/whatsapp.tpl on line 18

I have tried removing the extension and doing a fresh install, but  keep getting the same error message.

Does anyone know what it means?

OC2.0.1.1

Hello, Bint Ahmed,

A new version of the extension was released. Please test it and let us know if the issue still persist.

How can I completely remove this module from my site? I have selected "uninstall" from the module list, but I am still seeing errors regrading this module in my error log:

Undefined index: ButtonDesign in ........../public_html/catalog/controller/module/whatsapp.php on line 32

 Undefined index: content in ........public_html/catalog/view/theme/default/template/module/whatsapp.tpl on line 6

Hello @Bint,

You can take a look at the Uninstalling / deleting a module section in this blogpost: https://isenselabs.com/posts/how-to-install-or-delete-modules-in-opencart-20 and get an idea what you should do in order to completely unistall a module from your OpenCart store.

I hope this helps!
