Shahjada, thank you for the solution! The only place I saw HTML tags in Settings was under Messages. I deleted everything from “Download Limit Exceeded Message for Packages” and “Login Required Message”.
After clearing these out and changing the File Browser Root path back to default, settings saved right away. Upon reload, the “Login Required Message” code came back, but the “Download Limit Exceeded Message for Packages” code was empty. I tried to put it back in and it failed to save. I removed the <i> tag for the exclamation triangle and just left the text, “Download Limit Exceeded!” That seemed to work perfectly! Thanks again.
