A potentially dangerous Request.Path value was detected from the client (&).
Hi All,
I have upgraded from 2 to 4.5.2 successfully.
But I am getting the following error when I click on PDF link in media folder, which has '&' in the name.
Server Error in '/' Application.

This is a common problem, which the quickest solution is usualy to just rename the file to not contain an "&" character. I think others have also written event handlers to automatically rename files when one is saved to remove ilegal characters.
If you just need to get it up an running though, I would just say rename it.
We have multiple sites on one install with hundreds of images many of which have & in the name. renaming these is not an adequate solution as it would take hours to track down all the images and rename. is there another solution for this?

Hi David,
Could you not just run a batch process to rename all files?
Matt
wouldn't that break the path in the db that the file points to?
Hi David,
Then do search and replace within the DB? (Making sure to limit by media file types)
Also, just make sure you back everything up beforehand.
Matt
is working on a reply...
