PHP Fatal error: Call to a member function check () on a no

Hi, thanks for your interest. I am seeing such an error when I look at the logs from PLesk: PHP Fatal error: Call to a member function check () on a non-object in C: \ Inetpub \ vhosts \ trendbirter \ httpdocs \ catalog \ model \ checkout \ order. Php on line 267

I am getting such an error at image below while OpenCart complete the pay option. How could this be solved? hi when I want to click Continue button to continue the order after i finish my payment method then it goes to Checkout Confirmation" The continue button to checkout confirmation does not function it freeze like no action to take. but i look in code. i go to some javascript code. to continue it i try to trace which action it will take i think this javascript

They have the same problem with me. They have solved the problem here, but I do not know how they do it Opencart Fatal error: http://stackoverflow.com/questions/1273 ... 6_41827508

NOTE: This problem started after installing the "VQMOD" and "QUICKCHECKOUT" Modules. I'm using Opencart 2.3x

Is issue coming if you disable Quick checkout module?

If so, we recommend you to contact quickcheckout module developer.

I tried it out of my fast payment module and tried it again. I removed the theme completely and tried again again.But it did not happen again
