Using restora template with sp page builder (subscription) installed with a quickstart package. Seems I cant install anything additional, no language, no JCE editor.
Error for language shown is: Missing field in database: Joomla\CMS\Table\Language lang_code.
Error for JCE: Extension Install: Missing field in database: Joomla\CMS\Table\Extension element.
Furthermore I just see, that I can't even save my license key!
Error: danger Could not save data. Error: %s
Next: Dashboard shows "unknown extension". Clicking this, the following error cimes up:
n error has occurred.
0 Missing field in database: Joomla\CMS\Table\Extension   extension_id.
Also, the quickstart joomla version is 4.0.3.
On the dashboard it sais "Joomla is up to date", which can't be true ...
By clicking this, same error as above comes up.
Any idea what's going wrong here?
