Drupal 8.x

I have a Drupal 8 site with Bootstrap 3 theme.

I created a homepage with a newsfeed. Whenever there is a publication on the site, it generates a message in the newsfeed. The messages can have the status read or unread.

I want that when the .action-flag class is in the page, an animation is applied on the logo of the site.

The CSS and JS file is included on all pages of the site.

The .action-flag class is only on the home page, when a message is not marked as read.

Hi there,

I would like to confirm regarding data import.

I correctly imported image by CSV through "Feeds" however it wasn't displayed on Media list.

After I pushed "item" link and edit the imported media, it would be reflected. 

I cannot understand why the data wasn't reflected immediately after import.

Could you please let me know how to reflect the image data to Media list immediately without editing. 

After updating my drupal installation I get the 500 Internal Server Error and the whole site is dead.

I followed all the instructions to update manually here https://www.drupal.org/docs/8/update/update-core-manually

The original installation was done automatically by 1&1 ionos, I copied it to a test domain, where it worked correctly but when I updated the site broke.

Any ideas about what could be happening or how to troubleshoot?

I'm developing a module , this module will need some php packages from packagist.org.

Where should I install these packages ?

Should I install it in the vendor folder next to the docroot ? Or install it inside the module folder?

I think it might be better to install package inside the module folder,  unless this package will be used in other modules.

Thanks for your advice.

I have a multisite Drupal 8.x application, wherein I don't have access to hosting server; can I have a global redirection of add "www" to only one of the multisite application. 

Not having access to the server, restricts me to amend ".htaccess" and "apache" configurations. 

Hi all,

I know this topic is old and tired... 
But I really need some good metrics that discuss using Windows vs Linux as a host O/S for Drupal 8 in Dev/Prod environments.

I know I CAN (and have) installed Drupal in Windows...

Is there a general feeling that one is better than the other?... In development or production environments.
Which is recommended and why?

Does any good rationale exists for choosing Linux or Windows?... that isn't down to personal choice?
