I hope you are well today and thank you for your question.
I could confirm the issue on my test site, therefore, I notified the theme developer about this so that it will be fixed.
The issue will be fixed ASAP.
Thanks a lot!
Another related question, through the WPbakery builder I can use many blog post widgets to get blog posts on my pages (like: Blog Post Basic, Blog Posts, etc). Is it also possible to determine the excerpt length for when I use those individually? For example on a page I’d like to use the same ‘Blog Post Basic’ for different uses and sources, and also use different excerpt lengths for those uses. Maybe through css or php?
No, those WPbakery builder elements don’t provide an option to determine the excerpt length.
To achieve this, you have to develop custom code in the child theme of Gillion theme.
Developing custom code for custom functionality is beyond the scope of support that we provide here. Please see https://themeforest.net/item/gillion-multiconcept-blogmagazine-theme/19470306/support
If you are not a developer then you can consider hiring a developer to develop it for you. You can hire a developer from any freelance site. Shufflehound recommends the developer https://www.upwork.com/freelancers/~011652ffec8865c6d5
