When I try to add new content ( http://theorichel.nl/admin/content )I get this error: 

EntityMalformedException: Missing bundle property on entity of type file. in entity_extract_ids() (line 8043 of /home/customer/www/theorichel.nl/public_html/includes/common.inc).

But http://theorichel.nl/node/add/article works fine.

Any help would be much appreciated!

I have multiple D7 sites that are the same version, same configuration, but one of them does not have a time field for entering a Date. Year (by default), Month, Day, Hour, Minute are all checked in the settings.

Date & Time fields: https://imgur.com/a/0wwnWa4

Date field only: https://imgur.com/a/0hInVcZ

Has anyone encountered and fixed this before?

I'd like to add in the name field from an entityform to a mailchimp list via the mailchimp automation module, but I'm not sure how to code this.

I have a D7 site that I'm rebuilding in D9, and I need the theme ported to match the code upgrade and to be made responsive/ mobile friendly.

I'm using drupal 7.55. I've added a webform on several pages using an entity reference of a webform. However, i'm not able to view it as an unauthenticated user but i can view it as authenticated user. 
I've carefully checked roles and permissions several times for this entity reference and it is set to admin role as well as anonymous users.
What else can i do regarding this ? Please help thanks.
