Hello @kof456

Had you created extensions for all themes previously or not?

Daniil.

After I created the new theme, I could not use the create theme extension Option .

Which version of CUBA Studio do you use?

I have use CUBA Studio version of 6.9.0

Thank you.

Could you clarify whether both halo and havana extensions were created or not? I mean that this button become disabled only when halo and havana extensions exist.

Moreover, “Edit Halo theme variables” action is available only if the halo theme extension is created.

In case of custom theme creation (second action in dropdown) you are still able to create theme extension.

Please check your case with a new project

Regards,
Daniil.
