Hello SeolNam Ko,
Okay!! We appreciate your work and that you have a great experience.
But we are here to help you if you feel any problems then please update us.
I already did it. but nothing change.
Today I find reason. The resaon is pagespeed module in php.
The pagespeed module kept old js file.
I turn off the pagespeed mod and no problem now.
Thank you for your reply.
I want to get rid of the help icons that appears in the lower left corner.
The user manual says it disappears when I comment out the handleSupport() part of the custom.js file,
but it doesn't actually disappear. What should I fix?
I'm using Bootstrap 5 version.
