Under 'Layout', some field width is too short, I cannot see what did I put in it.
See attached files.
Strange, it seems like I was unable to replicate this in my locally.
And I was unable to login from your site again, can you re-activate your user account and update your FTP details at your first post so we can better have a check?
You're right, when i switch to this screen resolution then i can reproduce this issue.
If you really want to use this small screen resolution 1366 x 768 during editing your setting, i would suggest you zoom out so it will show that field properly.
Ideally, the settings should work fine regardless of your resolution but at the very least, it should have a width of 1280. I will create a ticket for this in our issue tracker and our designer will look into this.
