Disqus import: cannot create gzip reader
I was trying to import comments from isso. To do so I exported isso comments to disqus export format using https://github.com/angristan/isso-to-disqus. I put export.xml in the root of my webserver, but I'm getting this error:
domain_import_disqus.go:75 domainImportDisqus(): cannot create gzip reader: gzip: invalid header. What can I do to solve this issue?
