1.17.6 Errors on Opencart 2.2.0

[Hyrograsper]

Support,

We just purchased The One POS Premium and once installed, we receive multiple errors on the customer side of the website after adding a product and completing and order on the POS side. The errors seem to be on /catalog/controller/common/cart.php. It seems like it is session related because when the browser is closed the website will work once again. I have attached images of the errors.

Thanks,

Hi Tyler,

You need to avoid to login to backend and front end at the same time using the same browser. For example, if you are using Pos in Chrome, you can open your front end in Firefox.

Please send your admin and ftp login details to sup...@pos4opencart.com for us to check if you still have problems.

Regards,

Jason
