When logged in and I go to the extension page I get the error: A critical error has occurred. Wrong Local header signature: 0x78F5CF50

Event log:

As far as I can tell, this only happens on the Host\Extensions page, but that is a bit of a problem for me.

Hi Don,

It sounds to me that you likely have a corrupted zip file somewhere in your set of available extensions.  Look through your files in the subdirectories under /Install and see if this might be the case (e.g. a culprit might be a zero-length file).  You may need to check more than one directory; for example, available modules are located in /Install/Modules and skins are in /Install/Skins.  Further, the available extensions will have a .resources extension, but despite this they are actually ordinary zipped files.  You should be able to ignore anything that does not have this extension.

If by chance this does correct your problem, I'd also suggest creating a work item over at support.dotnetnuke.com.  This behavior should not be occurring for corrupted extensions, and should be corrected.

Hope this helps!

Brandon

Brandon,

I will post at Support as I didn't see any corrupted extensions.

Hi Don,

Glad to hear you were able to sort your issue out.  I have created a work item to remedy this issue so that this will not happen to you (or others) in the future.

Best,
Brandon

Unfortunately I posted too soon.  It didn't actually correct the problem.  I created a ticket in Gemini.
