Wolfram online help pages waste so much white space at the top. This really should be fixed.

Here, I fixed it, using Paint.exe

I hate wasted white space on web pages.

They could have been more graceful about handling ListPolarPlot[{}, PolarAxes -> True].

@J.M. That's an understatement

@b3m2a1 I ended up doing something like mapSymbols[f_, expr_] := MapAll[Replace[x_Symbol :> f[x]], expr, Heads -> False]

Even Heads -> False seems unnecessary.

any one knows if Mathematica gets automatically updated when one is connected to the net? I am asking, because I just tried same command I did 2 weeks ago, and now it works. On same version 11.3. Clear Kernel and all. I do not understand how this can be possible. Before the command (DSolve) did not evaluate.

@Nasser The explication could be here

@J.M.needshelp. @b3m2a1 You both don't get the point. ListPolarPlot[{}, PolarAxes -> True] is syntactic sugar for getting a list of all error messages that exist in Mathematica.

@Nasser I saw that. It's possible for a function to be updated by a paclet but usually that type of auto-updating is handled by the function itself and so generally is not implemented by the core-language, with the CloudObject functionality as a glaring exception.
