Drupal 8.x

Hi
Searched for a fix but cant find anything recent.
I have installed 8.1 and works well but after trying to upload new header logo (40kb) i get a white screen. IK can go back to previous pages but nothing else.
/admin/appearance/settings/bartik

I cleared cache but doesnt help.
Navigating back to the upload image nothing has saved. I get the same white screen everytime i try and image is never loaded.

Also changing colours in bartic dont update either.

Any help would be appreciated.

Hello,

I just updated my site from 8.0.6 to 8.1.0 without any errors. My sites report status had not issues.

My site looks fine when I'm not logged in (i'm the admin). When I log in I lose all styles. It's only text, images and hyperlinks. I have a vanilla LAMP server. My drupal site is all out-of box except I enabled the forum, but never created a forum. I did some minor color changes, icon and main site image changes.

Bartik 8.1.0 (default theme)
Seven 8.1.0 (admin theme)

Hello,

I'm writing module called bb generating a list of forms.

The ajax part should give a message but I only get :

Uncaught PHP Exception Symfony\\Component\\HttpKernel\\Exception\\HttpException:
"The specified #ajax callback is empty or not callable."

What am I missing ?

here is ModuleController.php calling the SessionHorairesForm.php below

I want to output a google map div with a side panel in my drupal 8 moodule. So no need for blocks surrounding my main content.

The question is how do I tell Drupal to only render main content using a Twig template of my module without outputting the entire Drupal theme stuff a long with the menus and the blocks?

All online materials I found so far talks about concepts behind Drupal rendering mechanism and render arrays but none really tell something about their implementation.

Hey guys,

this is my first post and hopefully you can help me with my first issue ;-)
I am using Drupal 8 and would like to show a short info layer on each site. I decided to use a module for that because I will have some backend logic to administer the layers content. I created a EventSubscriber with the KernelEvents::REQUEST option. The request itself is working but unfortunately I do not know how I can return / render the layers content inside a twig template. So what do I have to return to get the info layer working on each site?

In the past with Drupal 6 (I have skipped 7 so far), I ran various sites with a common codebase using the following structure:

sitename.com
  |
  |--cms (symbolic link to drupal directory)
  |
  |--Other stuff I might want on the site

i.e. in each site, there was a subdirectory called CMS that was actually a redirect to the base Drupal folder.

I liked doing things this way, as it let me (if required) install other stuff on the same domain without it messing with the main Drupal install.
