Sorry to bump an old thread but I created a child style and made a few modifications (mostly just colors and logo). Now the reply box is completely absent from every thread, PM, etc.
Can someone help?
Here's a link to my FORUM. Also below is a screenshot of what I'm seeing.
It looks like your server is using PageSpeed.. and if so, there are rules that you have to have in place to prevent some problems with loading of JS and whatnot. Check with whomever is in charge of your server - they should know what it is and how to tune it (if not, it's time to get another admin for the server or move hosts).
