Maximum call stack size exceeded

Hi,

i have VirtueMart 3.0.12 and Joomla! 3.4.5.

I install awocoupon, i click to com_awocoupon -> coupon, and "New from" header, don't work, i receive error "Uncaught RangeError: Maximum call stack size exceeded" core.js

window.submitbutton @ core.js:1
window.submitbutton @ core.js:1
window.submitbutton @ core.js:1

Hello,

What version of AwoCoupon?

Version: 2.4.6 pro

I am not having issues with that version. Is it possible to see screen shot, or if you prefer you can send private message with temp admin access for me to look at?

In Chrome incognito tab works ... I return in 1-2 days. Thanks
