I finded changed webchat plugin

But I do not have enough knowledge of what to do with it in order to get a new webchat.war

Good Day

I have same issue. Could someone help to compile war?

I rolled back to version 4.1.4 getting a lot of problems in v4.4.0. Somehow not working webchat, not reconnecting spark after hibernate, not correct transfering files, lack of necessary plugins on the new version, etc. reasons.

This problem does not interest me anymore, I feel that the existing solution will still work for some time. Then this functionality will be replaced by the company’s internal software. For example, the corporate chat is already inside CRM.

I’m sorry that there is no reaction from the developers of the plugin and server. But I understand that our priorities are different, so no offense.

Thanks for your work
