Hi,
1. Known issues will fixed on next release.
2. There is post cover image, you are able to update or remove it thru post cover http://take.ms/01cIS

Thank you
I mean that there are many items in media management that are't working.
As of "this post", and even I put my image in the post, but I can't see it in edit area.

Hey Wu,

Ah, there is actually a bug in EasyBlog currently when you have configured EasyBlog to use the built in editor but try to edit a post (that was not created with the built-in editor).

Temporarily, you can set the default editor to be TINYMCE to temporarily solve this but this would cause new posts created to use the TINYMCE editor instead of the built-in editor. We will be pushing out 5.1.15 soon to address this.

Thank you, Mark.
You always provide help quickly

You are most welcome Wu, and thanks for being understanding
