I'm really puzzled. My only thought here is that it may be platform-specific then. Are you using MAMP or something else for the local installation?
I've placed the .mov screenshot video plus a few more screenshots of other info in the shared drive folder I gave you the link to. Have a look if you want.
one of those screenshots shows (through phpMyAdmin) the contents of the jux_timeline_module database entry. I notice that the content field is empty. Should it be?
Setting the position to main-top now returns me to the simple listing display, e.g.,
1545
- Council of Trent (to 1563)
1536
- last proposal of duel between princes
which can expand and collapse. So the .css issue is still there.
BTW, I've discovered another problem. I cannot update the jux_timeline_pro modules from the admin interface. I have to use SQL or the myPhpAdmin to do it. When I select "Save" or "Save and Close", the module does not get checked in. This is a separate issue and I will open a separate ticket for it in a bit.
