Recently been faced with an issue in OpenCart 22.214.171.124 which seems to affect these versions:
Opencart Version 126.96.36.199, 188.8.131.52, 184.108.40.206, 220.127.116.11, 18.104.22.168
The Erros is this though:
addModule is not defined
The problem this error will cause for certain will be that you cannot make / add new banners to your opencart store, this will affect anything and everything where you have hyphen’s and other special characters – for this reason – remove hyphen’s and special characters from your product options, categories and banner names and so on.
I’ve posted this on the BUG on the OpenCart 22.214.171.124 Bug Thread
