Hi,
I use J3.4 and new installed Komento 1.8.3 While I was checking broken links in my website I realized that
components/com_komento/assets/css/common.css
has links such as
components/com_komento/assets/icons/message-warn.png
But there is no folder named as “icons”. Furthermore
message-warn.png , message-info.png, message-alert.png, message-tick.png, calendar.png, arrow-right.png do not exist. All of them are expected be in “icons” folder under the assets folder.
Similarly shade.png, closeme.png, button.png do not exist. All of them are expected be in non-existent “dialog” folder under “assets/images” folder.
Likewise j_button2_left.png, j_button2_right.png, j_button2_image.png, j_button2_pagebreak.png, j_button2_blank.png, j_button2_right_cap.png, j_button2_readmore.png do not exist. All of them are expected be in “images” folder under “assets” folder.
Eg: /components/com_komento/assets/images/j_button2_readmore.png
Since I have not touched those folders, assuming a bug, I wanted to inform you. Common.css refers those pngs that are non-existent.

Best regards..
