I would disable the Horoscope module to see if things go back to normal. You don’t have to delete anything. Simply add disabled: true, to the config entry for the horoscope module. Save and run MM and see what happens.
EXAMPLE:
{
disabled: true,
module: "MMM-YourHoroscopeModule",
position: "top_center",
config: {
maxWidth: "75%", // Sizes the images. Retains aspect ratio.
style: '1', // Style number or use ownImagePath to override style
ownImagePath: '',
}
},
