Hey Linard,
I’ve been unable to replicate this error so far – would you be able to send me the login/password from the WordPress backend? This will help me to find the solution quicker, as well as to test the second problem you’ve written about in a separate topic. You can send the details to support[at]satoristudio.net – no disclosure guaranteed. Also, please indicate the URL of the page where the VC shortcodes do not render properly. Thanks!
Sincerely,
Andrii / Satori Studio
