"I noticed that on a ultra HD screen the position of the front page 1 widget is largely overlapped by the front page 2 widget so that it pretty much disappears out of sight."
Can you post a screenshot of what you’re seeing? We would need more information in order to be able to see what the issue might be. I’m looking at the Aspire theme demo on a large HD monitor, but everything looks fine on my end.
You should be able to start a New Thread by scrolling to the bottom of the Theme/Forum you want to ask your question in.
If you start a thread and someone replies to you and you’re unable to reply (even though you’re logged in), just hit your Reload button on your browser. Some users experience the Reply box disappears when trying to reply…..but reloading the page should instantly fix that.
