sales/customer report throwing error on hosted server

v1.8

I'm getting the following error ( which I presume to be a permissions error ) when I try to run the new reports on a hosted environment ( they work fine on local machine) but I can't figure where I need to give permissions - my assumption was that it was the chart image which was causing the problem ( images folder has required permissions ) so if it is the chart image, is the chart image being saved somewhere else ?

any comments would be welcome

Hayden,

Do you have the following app setting in web.config file - <add key="ChartImageHandler" value="storage=file;" /> (it exists by default)?

You can also look at the following posts:

and

Thanks for that Andrei -

problem solved.


yes,

<add key="ChartImageHandler" value="storage=file;" />

was there in web.config.

There were a couple of solutions to my issue ( both about permissions )

- the easiest one  was to grant NETWORK SERVICE write permissions to the  application root

thanks again

I am having this same issue in version 1.8.
Can you tell me exactly which folder needs the Network Service "write" permission. I tried granting it on the root folder and it did not work. I am hosting on Arvixe if that makes a difference. Thanks for your help!

on dotnetpanel

it will be the folder

wwwroot

you can take it up with arvixe directly they apparantly have a nop liason/specialist

it's not possible to give write permission to whole root folder in plesk. but it's possible to do so for a subfolder. how can i specify a subfolder as the temp folder for chart handler relatively? (it's a hosted environment) say i want it to use folder "chartimagehandlertemp"

oh so soon to find the solution.
<add key="ChartImageHandler" value="Storage=file;Timeout=20;Url=~/tempImages/;"/>
