I have 3 errors (2 are "ReferenceError: Can't find variable: $" with index.php line references - lines 198 and 287). The other is "Failed to load resource: the server responded with a status of 404 (Not Found)" referencing https://helmet-decals.com/includes/t.../sb_header.png. (which doesn't exist)
Did you apply the changes that @DrByte suggested in post #264 of this support-thread?
