I just noticed an issue I didn’t observe before the last Sparkling theme udpate.
The problem is that when I create a new page, it doesn’t display the correct sidebar.
For example, this is an “ancient” page displaying the “correct” sidebar (the only one I have specified in widgets settings page) : http://bloculus.com/mes-lectures/
And this is a new page created for testing : http://bloculus.com/test/
As you can see, the sidebar is totally different whereas the settings in the page are exactly the same as the “ancient” one.
Hope you are having a good day and thank you for your question
Looks like checking several things in the backend is necessary, please send me your access credentials along with your website URL and I will investigate this case.
I have tested it on my test site and it’s working fine for me using latest version of Sparkling theme .
This can be child theme issue on your site so to confirm it just temporary use the Sparkling theme instead of child theme on your site. If everything works fine then it’s your child theme issue so just share me your child theme so that i can troubleshoot it.
Also this can be due to plugin conflict on your site so please try temporary deactivating all plugins and see whether everything works fine and then enable the plugins one by one to see which plugin is conflicting if any.
