An AJAX HTTP error occurred after installing _example data module [#2629582]

hi,

i got the following error after installing the_example data module

An AJAX HTTP error occurred.
HTTP Result Code: 500
Debugging information follows.
Path: /batch?id=44&op=do_nojs&op=do
StatusText: Internal Server Error
ResponseText: {}

I tried to clear cache with a wsod as the result.
I tried to uninstall it with a wsod as the result.
After uninstalling i tried to clear the cache again with a wsod. It is no longer listed in the installed modules list but it is definately not uninstalled correctly because i cant uninstall the transaction signing module, which is required by _example data.

Unfortunately i cant visit my dblog because of the wsod. But i had an open window with the dblog befor trying to uninstall the module. It is a php error

"Drupal\Core\Database\DatabaseExceptionWrapper: SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'unique keys ) ENGINE = InnoDB DEFAULT CHARACTER SET utf8mb4' at line 1: CREATE TABLE {unique keys} ) ENGINE = InnoDB DEFAULT CHARACTER SET utf8mb4; Array ( ) in db_create_table() (line 574 of /var/www/web335/html/bwo/core/includes/database.inc)."

So i deleted the module via ftp with the result that i'm no longer to do anything on my site. I also deleted all mcapi tables with phpmyadmin and i truncated the cache tables without result.

Any ideas whats the problem and how i can gat to a working site?

The example data module is just removed from the package - it shouldn't be present.
On on the final installation options form you can now choose to enable all the sub-modules + example data.
This uses devel-generate plugin.
You can also generate example content at admin/config/development.
However please note that I had problems getting drush to see those commands.
Do stay in touch!
This package is under active development and there is a responsive theme on the way also.
I'll get to 8.0.1 in a few days.
If you want to tell Drupal that a module is NOT installed, you can do this (in devel/php)

Drupal::configFactory()->getEditable('core.extension')
->clear("module.MODULENAME")
->save();
drupal_flush_all_caches();

ok...for now i had to delete my testdrupal installation and the database because nothing worked. I think i'll wait for one of the next releases to test the module. Or i just don't enable the examples data modul.
