I have successfully installed the Drupal 8.5.3 demo version, however I am getting errors when updating some of content. I can update system variables like the Basic site settings, social media links in the themes footer section. However, I cannot modify an existing page or create a new Basic page or Article.

Here is an example of the error message I get:

The website encountered an unexpected error. Please try again later.InvalidArgumentException: Class “Drupal\Core\Entity\Plugin\Validation\Constraint\EntityUntranslatableFieldsConstraintValidator” does not exist. in Drupal\Core\DependencyInjection\ClassResolver->getInstanceFromDefinition() (line 24 of core/lib/Drupal/Core/DependencyInjection/ClassResolver.php).

I need help please with some theme issues, like hero image and other things… is anybody doing some support here?

I still waiting a response for my theme issues…

Hello there, i already purchase this theme, but i have several questions about design. I created a ticket a month ago with no anwser anybody could help me?

I encounter the same problem as alexpastushok and Arttuhak but on all browsers, chrome, IE, opera, filezilla!

I get a orange screen.

i had sent a ticket to COCOON support #1565

i can’t work. Help me please

I have the same question of “grime101”, Do you plan to update your template soon. Because having a non-responsive “masthead picture” is a shame for a responsive template.

This looks really, really nice. One thing I noticed – the masthead image: background:url(/drupal/vanessa/1/sites/default/files/2016-05/masthead_0.jpg) does not seem to resize in mobile view. Is it meant to be this way?

Hi, Does this theme exist for Drupal 7? Also curious about the contact form. Is it possible to add more fields to that form?

Very nice template and very good support by installation in short time! Thank you!

Hello! I made a ticket about the same Internet Explorer problem mentioned above. Thank you

The theme with fresh install doesn’t work in IE 10 and 11, tested with apache and nginx..

I have contacted you thru support website but you haven’t reply me.

Alex

The description for this theme says video backgrounds are available. I can’t find it in the demo. Can you please send a link?

Hello! Tell me, where you can view information about the included modules Drupal for your themes? This is an important question in the distribution. Maybe there is a demo admin access?

hi , nice work … your theme I really like … I would like to know if it is possible a multipage version ?

GLWS

Nice design and beautifully built also, GLWS
