Hi,
I got a problem, that there was no login form at the backend. Fresh installation, requirements has been matched. After some time for debuging I found the problem. In the file:
themes/Backend/ExtJs/backend/base/component/Shopware.form.PluginPanel.js
at lines 88 anf 89 the quotes are formatted. After replacing them, it works for me.
//saveFormSuccess: '{s name=form/message/save_form_success}Form „[name]“ has been saved.{/s}',
//saveFormError: '{s name=form/message/save_form_error}Form „[name]“ could not be saved.{/s}'
saveFormSuccess: '{s name=form/message/save_form_success}Form "[name]" has been saved.{/s}',
saveFormError: '{s name=form/message/save_form_error}Form "[name]" could not be saved.{/s}'
