Have updated svManager to the latest version and all works ok!
Another question: Is there any way to convert simpleviewer galleries to juicebox? I have 100+ SV galleries with descriptions etc., and would be a pain in the ass to have to re-generate them all!
Would it be a case of replacing 'svcore' with 'jbcore' in each of the galleries? [edit: Nope, that won't work, just thought about it, doh]
Many thanks,
Jon
