I am using Aquamacs 3.3 GNU Emacs 25.1.1, and I got the error message 'Wrong number of arguments: setq, 3' every time when I trying to open a file the first time.
How could I solve this problem?
Thank you.

As I said in https://emacs.stackexchange.com/questions/28155/unable-to-update-packages-on-emacs-25-1#comment43164_28155 one of the changes in emacs is that now setq requires an even number of arguments. If you set the debug-on-error variable to t then when you get this error you should enter the debugger and see where the error is coming from. Adding nil as a final argument should resolve your problem.

2BTW, one can find news about this change via
C-u C-h n 25.1 RET C-s setq. Oct 31, 2016 at 11:08
I finally find the problem is caused by using 'subfigure' package in my latex file. And this problem has been solved by changing 'subfigure.el'. And specific salutation is given in thread on google groups. Hope this helps.

2This bug in
subfigure.elwas fixed in January. I suggest you install the latest AUCTeX version from ELPA. I don't use Aquamacs, but if it supports package installation from ELPA, tryM-x package-install RET auctex RET. Nov 2, 2016 at 14:23 -
@ArashEsbati: it used to work fine for a long time for me, but the error returned magically. Even with the newest AUCTeX version. Fixing the file
subfigure.elmanually helped. :-/– JanJun 18, 2018 at 18:06 -
1@Jan - It seems you have two AUCTeX versions installed. If you have the latest version installed, a manual fix would be impossible. Please check your HD for different installations. Besides,
subfigureis deprecated; consider usingsubcaptionwhich is also supported by AUCTeX. Jun 24, 2018 at 13:00
M-x toggle-debug-on-error, then include the resulting backtrace into the question.
