IIS6/7, medium trust, mysql, 2.2.9.6.

Sorry to bring up this post again. I'm the original poster who was having issue with the SharedFiles module.

I've now upgraded the same site to 2.2.9.6. Cleanly delete and upload all again except the Data folder.

However, the SharedFiles problem still exist. Whenever I tried to upload a file, I got this message:

We're sorry but a server error has occurred while trying to process your request.

The error has been logged and will be reviewed by our staff as soon as possible. It is possible that the error was just a momentary hiccup and you may wish to use the back button and try again or go back to the home page.
 

And the error log:

Please help as I need this feature as soon as possible. Or else could you please recommend another workaround or another module which I can use for user to upload files?

Best Regards

I've followed the document and rename Web.config from Web.MediumTrust.config, and after several checking, the relevant NeatUpload sections does already being commented out, except this part:

<add namespace="Brettle.Web.NeatUpload" assembly="Brettle.Web.NeatUpload" tagPrefix="NeatUpload" />

Do I need to comment this out?

The app_data\NeatUpload_Temp folder does already exist, but I'm having doubt it may not be writable. (since I told my host before only 'Data' folder need to be writable)

If that's the case, how can i explictly specify a different directory using the tempDirectory attribute of the NeatUpload element, as mentioned in the document? (Maybe I can specify it in the Data folder?)

Thanks again.
