I am not able to reproduce this problem using this macro on either ImageJ 1.51d or 1.50i:
newImage("HyperStack","8-bit color-mode label",852,720,8,1,4);
run("Split Channels”);

However, when we try to update we get the message 'The "News" page on the ImageJ website is not in the expected format or it was not found.' We also got the same error yesterday on a different computer.
You are getting this error with the Help>Update ImageJ command because you are running an older version of ImageJ that does not support the HTTPS encryption now used by the ImageJ website (
https://imagej.nih.gov/ij/). You can work around the problem by downloading the latest ij.jar file from
https://imagej.nih.gov/ij/ij.jar and copying it into the ImageJ folder. On Mac OS X, you need to control click on ImageJ.app, select “Show Package Contents” and copy the ij.jar file to Contents/Resorces/Java/ (or Contents/Java/ if you are using Java 8).
