Webpage Item dose not display charts on webpage

Asked by Paul J. Belter

Symptom - Web Page section displays site but charts show with boxed red x.
Attempted solution- Performed registry edit to force use of IE9
Xibo Environment - Server Ubuntu - Client Windows 7 x64
expected behaivior - web page item should display charts, The web page works outside of the xibo client.
Is there a setting somewhere that needs tweeking on the client side?

The web page was designed using VS2012. It is also using vb.net

Xibo doesnt do anything special when opening a web page - it just loads the URL in a standard web view control. Unfortunately there is not much beyond that under our control.

Could it be the server end refusing to serve those images when on an embedded page?

Perhaps you could check the server logs (of the iis box) and see what it is doing with the requests.

Thanks Dan, I think I had a brain cramp or something. the charts are stored in File Folder TMPIMAGES, this folder wasn't being shared so I shared it, the logs indicated that file not found was occuring when attempting to load the chart images. So I'll have to check this out Monday to see if it is resolved. What I find wierd is that I have a couple of rasberry Pi's out there hitting the same site with no issues.

Dan the charts are now loading, however this is not consistant. It must be a setting on the web site itself that needs tweeking. I actually got the site to display the charts by first opening the web page in IE9 on the client and then starting xibo client with the web page open. not sure why that worked but i'll keep plugging away at it. for now i'll consider this resolved and open a new one if I find a true solution.

Hi Dan, I thought I would update everyone on the issue I was having, It did appear to be a security setting issue for the folder where the chart images reside on the IIS server. Since tweaking the permissions I have managed to eliminate the occurances. Also I found that if your client is a windows 7 OS, it is helpful to disable the Windows Desktop Window Manager service to avoid an igdumd32.dll Fault. perhaps you add this as a suggestion on the client instalation for Windows.
