Dear @gagood ,
Thanks a lot for reaching out.
May we ask you to check the screenshot and let us know if we have inserted the same custom class as you did?

In case we did, we couldn’t see any error message.
May we ask you to follow the steps below and reinstall the plugin and try to use the same custom class again?
1. Please, navigate to the Settings section of the Popup Builder plugin:

2. Uncheck the ”Delete popup data” option and make sure to click on the ”Save Changes” button:
https://prnt.sc/vht1i2
This step is a must, in case you don’t want to lose all the popup data you have.
After, please, deactivate and delete the current version of the Popup Builder Plugin and install and activate it again:

Please, let us know if this helped.

Thanks for reply.
I inserted “hoge-button”, as the screenshot, but error message still showed.
Next I reinstalled the Popup Builder Plugin, but same error occured.
Dear @gagood ,
Thanks for getting back to us.
We guess, there was a misunderstanding.
We just wanted to make sure, that we have inserted the right custom class to test, since in your initial message you informed us, that you have set a custom class and got an error message, and thus, we wanted to set the same custom class to reproduce the issue.
Now, may we know what kind of custom class you have inserted so we can try it as well and see if we are getting the same error message or not?
Best,
Popup Builder Team
