Hi,

I have installed DNN on a shared host, softsyshosting, and although I can edit the existing pages, I can't add a new one because of the following error:

A critical error has occurred.
Request for the permission of type 'System.Security.Permissions.FileIOPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.

Unfortunately, it doesn't tell me which file or directory it is trying to write to, otherwise I might be able to resolve it myself - but is there a log file I can check, or does anyone have any ideas as to what might be the problem? I'm not sure how DNN works internally - if the pages are stored in the database or file system.

Thanks in advance,

Dave Harrington.

Hi Sebastian,

Thanks for the response. I'm not 100% sure what account the application is running under, as there is no way to check via the web control panel what are the app pool settings. I can change the file permissions for two users - my website (which I created - I'm assuming I don't need to create a virtual directory) and Network Service; I've given them both read and write permissions from the root, including their children. However, this didn't help. On the website administration, I've ticked "Enable Write Permissions" - not directory browsing as I definitely don't want that - but again this made no difference, even after stopping and starting the website. So, unfortunately, although I guess your idea is the cause of the problem, I am still not sure how to fix it within this environment.

Cheers,

Dave.
