    ZIP Upload problem


    I have a site with Umbraco installed on it and I’ve installed the ZIP Upload package.

    When I want to upload a zip, with only pdf files (no folders), it gets the following error:

    Server Error in ‘/’ Application.

    Wrong Local header signature: 0×21726152

    Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

    Exception Details: ICSharpCode.SharpZipLib.Zip.ZipException: Wrong Local header signature: 0×21726152

    Source Error:

    An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.

    Do you have any idea why it happens?

    It's about the ZIP upload created by Tim Geyssens: Doesn't anybody know how to solve this problem?

    I guess the zip file is invalid.

    Can you test with a clean (self created) zip file (with one text file or similar)?

    I think the ZIP file wasn't correct. Tried it with a new created zip and then it worked!
