Note that you do not need to set the option DisplayFunction to
Identity any more, for the semi-column prevents the output to be displayed.
line = Plot[secondfit, {x, 0.8, maxtime}];
splot = ListPlot[second, PlotRange -> All];
Show[splot, line]
The error message you get is because, at some point, you tried
(involuntarily) to assign a new value to a protected symbol. In other
words, you have some syntax error(s) at some point in your code. It is
hard to tell more without the actual code.
