Yesterday got an OpenCart script + plugin installation request to our installaton department.He requested us to install Opencart Version 126.96.36.199 because the plugin The ONE POS will not work with latest version.
OpenCart installation was very easy but got errors when i install the plugins.
First I installed The ONE POS 1.3.5-LT plugin and got error as popup.
SyntaxError: JSON.parse: unexpected character at line 1 column 1 of the JSON data
I tried to fix the errors. But couldn’t find a solution and i told the client to send different version.
Then i installed The ONE POS-1.17.5 and but the plugin settings was not in admin menu.
The below step fixed the issue.
Admin > Extensions > Modification > Click refresh button
Installed TMD Import Export Module 2.2.x2.3.x. and got error
Undefined variable import in system/storage/modification/admin/view/template/common/menu.tpl
Again tried TMD Import Export Module 2.x and this time got permission error.
