I see my mistake. It was confusing to me how to apply the settings I had just changed, and I ended up saving the default settings. It would be good to change “submit” to “change” and make it less confusing regarding what settings are being saved.
P.S. Would you please make the text on your forum a little darker. I find it very hard to read. I have a little color blindness and the blue color may also be affecting the readability of the text for me.
