Drupal 7.x

hello

I have seen many websites for reading novels online. Especially novel reading websites built on WordPress.

But I haven't seen it in Drupal yet.

Because of that, I created a website for reading novels online on Drupal.

I have to say first that I am completely blind. Therefore, the website may not look very beautiful.

The purpose of creating this website is I want it in Thailand where I live. There is a website to read novels online. that the writer is visually impaired

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.
