I open a Content block.

Click on Add Image on the left side of the Edit window.

Click and Choose an Image

The Image appears in the edit window.

The HTML for the image:
<img src="/index.php/download_file/-/view_inline/9/" alt="test.jpg" width="71" height="70" /></p>

Update the block.

The text shows, not the image.

Edit the block again

Go into the HTML and take out the slash in front of index

Update the block and the image appears.

Obviously, I don't want the customer to have to edit the HTML every time an image is added.

What do I need to do to correct this? Is this a configuration issue?
