I have Regulus 2 as my current theme. Before not long, the 'Admin Options' feature was there, and I could find the 'edit this post' link under each post. But now it has disappeared, with the column on the right-hand side too which had "Write, ..etc".
Everything is enabled in the "Current Theme Options",
so what's the problem?
By the way, I guess this happened once I wrote some stuff in the 'About' column.
