To explain what's going on, when I try to make a ListLogLogPlot from a table of data, and I put in GridLines->Automatic, I get the following error:
"The value of the GridLines option should be None, Automatic, or a list of two elements.".
This is new; when I used this exact same code last weekend, I did not have this problem, and was able to get the grid lines to show. Since I don't really need the grid lines, but rather, the spacing in my ListLogLogPlot to show, I tried using Ticks, and the plot was created without errors, but no ticks showed up. Clearly something is wrong since a ListLogLogPlot should show ticks by default.
I've attached two screenshots, one with the GridLines error, and one when it accepts GridLines->None. I did quit the kernel and restart Mathematica to see if that helped, but it didn't. I tried to Google this, and having come up empty-handed, I decided to post here. Does anyone have any ideas as to why this is happening, or how to fix it? Any input would be greatly appreciated!
Update: Here's something really strange; I opened up my notebook in Mathematica 11.2, and the plots work fine, GridLines works, and I have a useful plot! It looks like it's only 11.3 that has a problem, and the problem is new. Perhaps I should reinstall it?
