Drupal 8.x

Exception: Only file CSS assets can be optimized. in Drupal\Core\Asset\CssOptimizer->optimize() (line 25 of /var/www/drupal-8.8.4/core/lib/Drupal/Core/Asset/CssOptimizer.php).

Any one know what causes this exception? and how can be fixed?

The side effect admin login fails showing website error.

"drush cr" fixed it, but it keeps happening.

Hi everyone!

I'm trying to add a button on a content type, I would like for all types of that particular type to have a button in that view to modify, edit or delete that node.

Thanks!

These modules were added (following the d.o upgrade documentation) to upgrade Drupal 8.x to 9.x 

Upon successful upgrade, do you keep the modules or do you remove them? 

These were the modules:

"drupal/core": "9.0.0 as 8.9.0",
"drupal/core-composer-scaffold": "^9.0.0",
"drupal/core-project-message": "^9.0.0",
"drupal/core-recommended": "^9.0.0"

This past week I migrated a site from D7 to D8.

Any nodes created before this appear to work as expected with the More Like This block (in that the block lists truly similar content).

However, this is not the case for any content created since the migration.

In this case the block only lists other content which has been created since the migration (and which has extremely little similarity apart from the post date).

This pattern of behaviour of the MLT block is consistent: old content works fine, new content doesn't.

I have reindexed many, many times.

Hello 

I need help with a business model am trying to build,

I was wondering how much of it can be done via drupal CMS and how much I can do via code.

I have a custom content type which authenticated users can post and link other users to it, 

What I would like to do is to have users accept that content type from contextual view block I made in their user account page,
