Well I think you hosed your custom styles.
The stock and dark green styles seem to be okay.
It may be best to start over with styles.
Your default style is looking for images that do not exist.
Using the coffee style I assume.
you never copied the background images to your site or deleted them from the style.
Also I can't figure out what you are missing or altered on your custom styles that caused the alignment issue.
it is not just the breadcrumbs but the footer and the topic also.
Somewhere you have either a weird width statement in css or a bad css class entry you entered in styles.
FYI,
When using old styles prior to ubb7.5.8 you need to edit it because there are additional css classes that did not exist prior to 7.5.8.
Usually in the style editor you will see a copy link next to them, That you can use to at least use some default settings to start with.
Also you may need to edit/add or delete the wrapper per style, again it is in the style editor.
Also when downloading a existing custom style. you need to also use the custom images placed in a special folder on your site. The style will tell you where to place them if they are needed.
