Hi,
I have tested it with 6.9 and a bunch of popular WordPress themes (some default WordPress themes, GeneratePress, Storefront etc.) and had no issues with either. So it must be something more theme specific. Let me know what theme you are using and I’ll add it to our ToDo to check 🙂
Thank you for your reply! I’m using the Twenty Twelve theme. The plugin still works, except when it’s a page set as the homepage. It also doesn’t work when it has its own template with a custom-registered sidebar…
Addendum: Twentytwelve theme with Classic Editor 1.6.7 and Classic Widgets 0.3
Hi,
I tested with Twentytwelve 4.7, Classic Editor 1.6.7 and Custom Sidebars 0.3, no issues for me (see screenshot https://prnt.sc/looSQQppJQ5B ) 🙁
Since you mention a fatal error, please check your server’s error log and let me know what the error actually is.
Thank you! I’ll continue testing and get back to you when I’ve figured out what the problem is…
