Hi,

I have a site with Umbraco 4.0.2.1 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.

Stack Trace:

Do you have any idea why it happens?

Thanx,
