Hi

I am getting server error while exporting RadHTMLChart into PNG

Could not find file at the path ....

same works fine with PDF but not with PNG

With so little information I'm afraid we can't help.

what is the complete error message ?
what is the path ?
does the path exist ?
is this the path to inkscape or the path where the png is supposed to go ?
do the pdf go to the same path ?
can the user/process access this path ?
...

Is this a problem with Inkscape??

A server error means that something's wrong with a website (very generally). Since Inkscape is not a web application, I don't know how we could help with a server error.

Maybe we have some members who know what RadHTMLChart is, and have some idea what you're trying to do, who can help, coincidentally. .....Unless this is something to do with the Inkscape website....although I've not heard of "RadHTMLChart" in any website discussions.
