Hello all,

I'm developing small things for Drupal 8.8 based sites. For that, I use a local Drupal installation (made with Acquia desktop) and I have two remote testing sites and two production sites. In fact, the dev I'm doing is for both of them. The dev requires to add some content, like articles and menus. The uuid of any of the five Drupal installation described above are all different but they all share the same Drupal core version (8.8.1).

Hi,

I installed Drupal 8.8.1 successfully but after some time I am getting following error, when I cleared cache. Any idea or help what could be causing this?

Look like cache-config table  is does not exist, when I verify MySql database table not exist message.

Getting table does not exist error message from below tables.

Cache_data,Cache_config,Cache_bootstrap

I did database updates using composer and drush but no luck.

Error:
