AJAX error with Configuration objects

[locutux]

Hi,

New local install of your WXT 8.x-3.010 tarball, on a new PHP 7.4.6 NTS and Windows 10/IIS.

When I try to access Media library on a page, or add content, I systematically get the following error:

An AJAX HTTP error occurred.
HTTP Result Code: 200
Debugging information follows.
Path: /core/install.php?profile=wxt&langcode=fr&continue=1&id=3&op=do_nojs&op=do
StatusText: OK
ResponseText: Drupal\Core\Config\PreExistingConfigException: Configuration objects (language.entity.fr) provided by wxt_ext_translation already exist in active configuration in Drupal\Core\Config\PreExistingConfigException::create() (line 65 of C:\testB\wxt-8.x-3.010\core\lib\Drupal\Core\Config\PreExistingConfigException.php).

Looked at similar AJAX errors in the Issues (like issue #138), but the error message was different. Could you please provide us with some guidance on why it is doing this? Thank you and have a great day!

You’ll find limited support options for windows based deployments here. I don’t know of anyone running Drupal8WxT in windows IIS. (Some for Drupal7 yes)

We recommend against it, suggest Apache or NGINX and MySQL or Postgres. Best of luck.
