Hello,
I just installed joomlacomment4.0.0beta2 is the only version that was installed on my site.
Everything works fine, except nackend, I is not the button "validate" and "save" the field is empty and white.
Therefore not possible to save the settings.
If someone can tell me how to address that I would be grateful.
Excuse me for my English, I am doing a translation on google.
