Drupal 8.x

I am getting the following error whenever anyone other than ADMIN tries to create a post in the forums on my site. This has occurred since the site creation and has persisted through a core update from 8.86 to 8.92. The forums work fine for ADMIN but, only ADMIN. Any ideas on what the problem is and how to resolve it?

The website encountered an unexpected error. Please try again later.

Hi guys, Trying to set up httpclientmanager via guzzle to make a service call to google cloud.

Hi,

According to this one

https://www.drupal.org/forum/support/post-installation/2016-06-06/drupal...

this still is a bug.

But more to that - I have View enabled. And I have pages that are "promoted to home page". View itself is not altered, but it does not display these pages in preview. And it does not allow a home page to be with '/' url.

I am new to drupal and need my webform submissions to be sent to my SQL server containing my database and table.  If my understanding is correct, I need to use the hook_schema() function in the Webform.install file to create a php object to represent my module submission data.  But I'm not sure where to go from there.  How do I get the submission data sent and stored in my table?
