OTRS and ckeditor (richtextfield)

[rickdohmen]

Hi,

We have recently updated to OTRS 5 with Nginx but if we use Richtextfield, the input field is invisible.

It is visible for a second and then is is gone. If we inspect the richText field in Chrome is hidden. Is we disable the hidden, the field becomes visible

<textarea id="RichText" class="RichText Validate Validate_Required HasCKEInstance" name="Body" rows="15" cols="78" aria-required="true" style="/* visibility: hidden; */"></textarea>

If we disable the Frontend::RichText in the sysconfig the inputfield is loaded immediately.

There are no errors visible in the nginx logfiles.

Could you please help us?
