Drupal 8.x

I installed Mailchimp, Mailchimp Audiences, Mailchimp Campaign, Mailchimp Signup modules.
I'm using the modules, and it is supposed to let you add a campaign, select a template and send it without to enter in the MailChimp UI.
The thing is I created a campaign and I selected a template, but in the content sections I'm not able to add content in the drupal 8 UI.

I'm not able to add content in the contents section if a select a template.
The only way to add content in the content section is if I have no template selected.

Hi there,

I want to make a photo-album using Colorbox (8.x-1.6). To upload the images I use Entity Browser (8.x-2.5) Dropzonejs (8.x-2.1) and File (Field) Paths (8.x-1.0-beta2).

It works on the off-line site after imlementation of a patch on filefield_paths.inc (#6 in issue #2858308). The thumbnail is shown, clicking on it shows the Colorbox slideshow.

Hi,

I am having a weird issue that I cannot troubleshoot, I want to update a 8.7.5 install to 8.7.14 prior to a final 8.8.6 update. This is for a production site that I have avoid downtime for. Because of this I tested a method on a dev server that went as follows:

Upload 8.7.14 core/vendor directories as different names, i.e. core8.7.14 and vendor8.7.14

Once uploaded, rename existing 8.7.5 core and vendor files, then rename core8.7.14 to core and vendor8.7.14 to vendor

run update.php

Hello I am using Ubuntu and my website works fine.

I have installed composer and drush globally and the both work. I added the devel module to the site.

now when I run: "drush fn-hook toolbar" or "drush fn-hook view"

a screen comes up, prompting me to select from an array of implementations.

When I select an implementation, this occurs:

I updated Drupal 8 using Composer. I got this error when logged in to admin. The Drupal version 
"name": "drupal/core",
"version": "8.8.6",

The website encountered an unexpected error. Please try again later.
