Hi I am having issues backing up my wikispaces files and pages.
I am going through the same process that i have done previously but have been unable to back anything up for the last few months.
Everything logs in as normal however cyber duck 'shuts down unexpectedly' and creates an error report.
I am unsure what this means and how to fix it.
I have copied the error report into a word document (attached).
