and another question, how can I add the .zip extension to the upload?
Hi,
You should be able to allow .zip extension from the plugin settings, Allow more file types -tab.
Regarding the first message, could you please send a screenshot or two, so I could understand better what the issue is related to?
Thanks. I’m currently working on a new version of the file uploader, which should work better across various server configurations.
The new version will be released during this month.
