[Xerte-dev] Re: FW: Further Xerte Data Loss

I'd investigate whether this line is actually doing what it is supposed to...

https://github.com/thexerteproject/xerteonlinetoolkits/blob/develop/modules/xerte/engine/save.php#L36

Though not sure whether a break in the upload would still allow save.php to complete...

We could try to rebuild the XML in save and validate that it is ok? and ends with </learningObject>

Regards,

John Smith | Learning Technologist
Room A251, Govan Mbeki Building | School of Health & Life Sciences | Glasgow Caledonian University

Please address ALL support requests to hlsblt at gcu.ac.uk where one of the School Learning Technologists will pick up the job. This will ensure that all jobs are completed as promptly as possible.

Is it possible that it's a unicode ` character?

I've seen a number of UTF-8 related issues with the data.xml etc files.
