The ‘Footer>Copyrights’ field in Theme Options was filling with rogue ‘\’ characters every time the theme options were saved. This was because I had used double-quotes instead of single quotes to specify the HREF and TARGET of an A tag I’d placed in there. In short, use single quotes, not double quotes to add HTML to the ‘Copyrights’ field.
Please check the permissions for css folder and inner files in the theme root on your server and get it adjusted to 775 and if you would still experience this issue then please submit a ticket with all access details so we could check on it and will help you getting it fixed.
