I am noticing a critical error in the admin panel logs.
An exception has been thrown during the rendering of a template ("Template "modular/slider.txt.twig" is not defined.").
I have searched the folders and I do not see a file name 'slider.txt.twig'. The only file that is close to the name is slider.html.twig.
Here is the rest of the error.
