New email windows or replies are not working for me after upgrading from Znuny 6.3.4 to Znuny 6.4.4. It's showing me a browser error. When I review it, I see some problem with javascript.
Version Znuny 6.3.4 did not have this problem.
I will appreciate any direction to solve this issue

Thanks!

Sorry, my mistake. Need to update version by version. Everything is OK now
