Drupal 8.x

Hi,

I have two content types (PPL Fields & Production), I have created a Entity Reference Field(using Entity Reference View to get filtered list of PPL Fields) in Production.

Today I did an upgrade to the newest version of Drupal 8 (November, 5th). Now I can not login anymore. I enter the user name and password and press on the enter-button. Instead of logging in the cursor jumps back to the login-field. I get no warnings or errors. Someone an idea?

On Drupal 8 I will want to create an invitation form, if possible using the contact module provided with the Drupal kernel.

I want the user to manually enter the recipient's email and select a template (an email template). Then he clicks "Send" and that's it.

I have already installed Swift Mailer.

I have already created 2 templates for the 2 models.

How to create a page with a contact form ?

To update a lot of old URL aliases and do them with the new format, you would run the following code:

Hello,

Now i want that name is a varchar(255) so i created a hook to update in mymodule.install
