Hello ther,e, recently we have a Secure Server Plus installation on the Centos 6 Server, 

we are working with Drupal 8,  the vendor notified that they

"  Some configuration changes were made to php through the php.ini file, including some changes that disabled certain functions that are often used to propagate malware. We also ensured that php error reporting is not passed to the user.  "

When loading the Drupal portal, we have: 

I have a simple tableselect element inside my form and the tableselect rows are populated using a pager as follows:

Hello, i have a problem with my drupal 8 page. 

I have created a view with:

• Thumbnail
• Title of the object
• Media type
• Year (taxonomy)
• Link to download
• Edit link for admin

This yields a table. With also 2 filters on Media type and Year. 

So now to my problem. 

When i use it as a plain table (no grouping used) i can use NO RESULT BEHAVIOR and when i filter on a media type which the table doesn't have or a year that isnt added i get a response. 

I am looking to build a Drupal site that is an eCommerce marketplace. I suspect from my research that it might require a mix of updated and seemingly outdated modules. The Commerce Composer Template + Theme + Sample Data doesn't really cover a marketplace option. If you have built or maintained a Drupal 8 or 9 marketplace site within the last 12 months, would you be willing to share your experience and ideally your code, theme, module list, or sample data? How has Drupal fared for you as a marketplace solution?
