I'm a using ShareLaTeX to write a report and it is almost perfect in terms of fails and warnings. There is only one warning left, which is the following:
I have searched online for a solution, but almost all says to remove the usepackage causing the problem. I just simply can find it. It is not in main or preamble, or any of the other document. I use the search function in ShareLaTeX to search for
fixltx2e, but I find nothing.
Maybe I'm looking for the wrong usepackge, and the mistake might be from another usepackage including
fixltx2e, but I don't know, which one.
I would really like to fix the warning, as it is the only one left. Anyone know what might be causing it?
