I deactivated the tagDiv Composer plugin and now works (i dont need the tagDiv – i use WPBakery).

Hi Simion,

Wordpress 5.0.3
Newspaper 9.2.2

When I create a new post there are no problems saving (with gutenberg editor).

With the old posts it gives error while saving (gutenberg editor is disable).

I reinstall the plugins and now the problem happened when I save a post.

Thank you Calin.

Works but on some elements not because they have different tabs.
Example: http://www.clipular.com/c/5950073125732352.png?k=wbyQwQNZC71M-xQtMb2VoHm4Gfk

I change the code (for WPBakery)
.vc_ui-panel-header-container .vc_general li:nth-child(3) {
display: none;
}

And for exceptions (Video Player example)
.vc_ui-panel[data-vc-shortcode="vc_video"] .vc_ui-panel-header-container .vc_general li:nth-child(2) {
display: none;
}
