Plugin doesnt work with new wordpress 4.5.2

Hi again.
I’m doing some tests and deactivating some other plugins, everything is ok.

Does second paragraph here: https://qtranslatexteam.wordpress.com/2016/04/23/release-notes-3-4-6-5/ help?

Dashboard (/wp-admin/) does not have LSB by default, which exactly admin page do you mean, or which plugin put LSB on your dashboard? You are using the latest qtx, right?

Good! Thank you and good luck to you in your further development!

Problems with teh pluging HeadSpace2

Deactivating HeadSpace2 everything is OK

The plugin HeadSpace2 is not maintained anymore: https://urbangiraffe.com/plugins/headspace2/. Give it up? There is a bunch of other plugins to work with metas. Besides, google does not recommend to use meta tags anymore either. Or fix it yourselves? Any errors in JS console? These steps may help: https://qtranslatexteam.wordpress.com/troubleshooting/
