But the moment I uploaded the new files to my Cpanel, I logged in backto my plugins page and saw the message “Invalid License Key” on top of my plugins page. And my plugins page didn’t show my complete list of plugins, it seems that it hangs halfway.. I quickly revert back to 1.3.5 and it is loading properly now. The reason why I upgrade is because in 1.3.5, the conditional logic is not working in my website now.
And also, in my Cpanel, I see that there is a plugin folder named “Quform”, I wonder what plugin is that.. I also have a plugin called “Quform Max Form Submissions”, I wonder if that is the issue that caused my plugin page to hand after updating…
