Hi @eltonheta,
Thanks for contacting us.
I’ve checked the Tab widget with Shortcode, it seems fine on my end (screencast). Three tabs with different shortcode template work fine. I would request you to check your shortcode to another area if it works.
In the meantime you can run a conflict test in your environment.
To do so, first of all, switch your theme to a default theme like 2020 or Hello Elementor and check if the issue still persists. If that solves your issue, that means the issue is related to the theme you are using.
If switching to the default theme also doesn’t help, please check for any conflicts between the installed plugin. To troubleshoot the issue, please deactivate other plugins except for Elementskit and Elementor to check if the issue still persists. If that solves your problem, activate the plugins one by one, and continue checking the issue In this way you will be able to detect which one causes the problem.
Let us know your update, please.
Regards,
Arif
