Not possible to insert picture using wysiwyg editor - Same problem in your demo.

Hello While trying to edit class/course/lesson/slides descriptions, in cases where I try to use the wysiwyg "insert picture" button I get to the box that ask me to "browse server" to find a picture. I then see those pictures I have uploaded in the Archive, but there is no way to pick a picture for inserting. There is no button that says "OK", or "Save" or "Insert" or anything, and neither its possible to just doubleclick a picture to select it. Thus I am not able to insert any pictures into the editor text/html window. Drupal log reporting says nothing, as there has been no action, no insert, or other button to click on, so all I could do was close out the filearchive window without having done any action. I see the same problem here in your own online demo. And I have tried with both Firefox and Chrome browser. I have installed Opigno 1.21 on a Ubuntu 14.04 server running Webmin/Virtualmin. Webmin/Virtualmin does not accept +FollowSymLinks, so I had to replace that option with +SymLinksIfOwnerMatch in .htaccess files in "private" folder and /sites/default/files folder. This worked well, but not sure if this make any trouble with inserting pictures and external videos into wysiwyg editor? Any idea how to solve this? Thanks onkli
