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:

Picture of the warning.

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?

    It is loaded by some class or another package. You can ignore this warning

If you use any package like \usepackage{dblfloatfix} or any package end with -fix, just remove those package and you will no longer get any warning.

    This seems like an arbitrary generalisation that might not always work.

  • If you remove \usepackage{dblfloatfix}, you won't get a warning, but you also will not get the functionality of that package (in this case, setting a double-column float at the bottom of the page).
