Small update regarding language confusion.

Since I implemented option to have custom language for each back office user. This option was also heritaged in widget/embed windows. This got users confusing, if I generated embed code for Russian why do I see english language? It was because the app remembered what language was set in back office. Since this small update, only site_admin will remember your language and you can easily test how widget in your language looks like without switching language in back office or using other browser.

If you desperately need this there is this github commit.

White screen while creating pro active chat invitation.

There was a bug in install script. And during pro active chat invitation creation you could get white screen. So just execute this query:

ALTER TABLE `lh_abstract_proactive_chat_invitation`
ADD `show_random_operator` int(11) NOT NULL,
COMMENT='';

This bug in install script effected 1.63v and 1.64v.
