}
Remove this "content: "f078"; /* down big arrow */" as this no needed here, and what is more it is written with mistake. It should look like "content: "\f078"; /* down big arrow */"

You have such code in custom CSS: Remove this
"content: "f078"; /* down big arrow */"
as this no needed here, and what is more it is written with mistake. It should look like"content: "\f078"; /* down big arrow */"
With kind regards.
