Wrong Editor view

@orakel,

Please see the screenshot below:

You have some js errors on your website. Those errors may from the other plugin or the active theme. Please follow the steps to get it resolved. 

Keep the console opened and deactivate the plugins/theme one by one and check after deactivation. The js error will disappear once the problem maker plugin or theme is deactivated. Once you find a problem maker contact the plugin/theme support and ask them to solve the error. 

@orakel,

Currently, if the pasted image has an absolute URL like this one: 

  https://example.com/images/mypic.jpg  

it'll be automatically converted to an image when a comment is displayed if the option called "Image Source URL to Image Conversion" is enabled. The option is located in the Dashboard > wpDiscuz > Settings > Comment Content and Media admin page. In short, using this option you can enable/disable image URL to image HTML conversion.

If the pasted image has the following code:

<img src="data:image/png;base64, iVBORw0KGgoAAAANSUhEUgAAAAUA
    AAAFCAYAAACNbyblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHxgljNBAAO
        9TXL0Y4OHwAAAABJRU5ErkJggg==" alt="Red dot" />

it'll be automatically removed. In other words, there is no way to upload an image directly by pasting it in the comment content.
