In the v1.57a version the footer appears to be messed up in the Spanish language. The link back to the site does not have the sites name from the "My Store" "Store Name" listed inside of it. Also the "powered by Zen Cart" appears to have problems.
The branch 157 will always refer to the current release version which is now 157c.

Yes, there was a missing closing tag on the store link. Fixed.
