Hi,

Update: Apparently this doesn't happen to version 7.2.6 (the initial version of the website).

I'm having the same issue. I'm using a shared hosting and set the permissions for all folders. The css and js's are working fine, except the images.

e.g.: ~/css/img/lowpoly.png ~/media/1001/antet.jpg?mode=pad&rnd=130893983430000000

This is clearly an issue with the ImageProcessor package that Umbraco.Core depends on.

Umbraco 7.2.8 used version 3.3.1 of the ImageProcessor.Web package (I don't have any issue with this version using the same hosting provider), and 7.3.0 uses the ImageProcessor.Web v4.4.0 (this isn't working for me).

As a temporary fix, we could just disable the package in order to be able to request images directly (and not have ImageProcessor intercept these requests). I have done some superficial testing and seems to be working fine.

I am trying to build the project to targe .NET framework version 4.5.1 (this is the version that my hosting provider currently supports).

Does anyone have any ideas as to why this is not working as expected? Any help is much appreciated.

Thanks!

Hello, i have save issue. How can i disable ImageProcessor.Web?

Thank you

I can confirm this issue on 7.3.0 as well. I am having issues on my host (aspnix.com) on every image request and intermittent issues on GoDaddy.

Commenting out the ImageProcessor.Web lines in the web.config is a hack for now.

I've logged an issue with the team - http://issues.umbraco.org/issue/U4-7433

Thanks for the reply and your interest in the matter.

One common aspect in all our experiences is the fact that we are experiencing this issue only when the application is deployed and hosted.

When running the site from IIS or IIS express on my dev machine I don't have any of these issues, but when I deploy to my hosting account, I run into the aforementioned problem.

I think it would be interesting to see what IIS configuration is messing with the ImageProcessor's ability to work correctly and see if we are able to control it

Hello, i have answer from shared hosting support:

Error:

System.Diagnostics.Process.StartWithCreateProcess(ProcessStartInfo startInfo) +1789 System.Diagnostics.Process.Start() +6814726

Becaose application tried to run cmd.exe with for us unknown command. This behavior is not permitted on shared hosting.

Hope it will help.

It seems that we won't see a fix for this any time soon. I guess we need to stay with older versions of Umbraco for now

I have contacted my hosting company and they came with the same reason for why we cannot use the ImageProcessor. It is trying to run cmd.exe which is not usually permitted on shared hosting.

I'll try to get some support from the developers of ImageProcessor and come up with an update.

I have raised this question with the ImageProcessor guys who were most helpful.

The component which cannot run properly in security restricted environments is the Post Processor.

This component can be disabled. In order to do this, get the ImageProcessor.Web.Config package from nuget and disable post-processing in the config/imageprocessor/processing.config (set the postProcess attribute to false).

The issue should be solved now

Hope this helps. Cheers

Anyone find a better resolution here on the steps to fix this? I just ran into the same problem with version 7.3.4. I didn't have the issue in 7.3.0.

Everything works perfectly locally. On the host (shared), the server complains with the same response as listed above.

Just update the ImageProcessor.Web package to the latest version (currently it's 4.5.0). The issue should be fixed.

An issue was raised on the ImageProcessor github repository. https://github.com/JimBobSquarePants/ImageProcessor/issues/268

Check the latest comment there :)

I'm running ImageProcessor.Web 4.5.0.0 now but I still have the same issue.

I updated using the Package Manager Console.

I installed the ImageProcessor.Web.Config too but I'd hate to disable a feature since it feels like a hack. I'd like to figure out what else I can do. Disabling it does work.

If I need to elevate permissions on my site or any environment changes though my Shared hosting provider is like getting a hot sauce colonic.

is working on a reply...
