I just added the multi-language option to my guide center, but I found when end users click the language option at the bottom right corner of the guide center, there will be an end user's sign-up pop up window showing up (This signup pop-up does not show up when end user refreshes the guide center until they change the language option in guide center. After the language option be changed, the sign-up pop up shows every time when end users refresh the guide center page).
Since the end user's sign-up function is not necessary to our current product operation, also because we need the web widget so I may not disable the option Anybody can submit tickets as indicated in this post. I have also disabled Require sign in as indicated in this post but it doesn't work. Hence how can I disable the signup function?
The signup pop-up in help center I want to remove is as the following screenshot, thanks in advance for the help.
