We have been using the EO.WebBrowser plugin for quite a few years now for hosting url's from 3rd party vendor. In mid-march, we suddenly began having issues where the browser opens, but the page is blank rather than showing the page from the url link. We have been unable to resolve. Has anyone else run into this issue? This is from a winform application, not web.

Hi, This usually indicate a crash inside the browser engine. Please update to the latest build and see if it resolved the issue. If that still doesn't resolve the issue, please try to isolate the problem into a test app and send the test app to us. See here for more details: https://www.essentialobjects.com/forum/test_project.aspxOnce we have that we will debug it here to see what we can find. Thanks

I have downloaded the newest version. It still is not functioning properly in our application, but i created a test project and it is functioning as it should. I am trying now to determine what is different between the application and the test project

I found out today that the url we are trying to host with EO WebBrowser has "same site attribute" turned on related to cookies.
Could this be what is blocking the rendering of the page and what should be done to mitigate this?

Hi,
We do not block rendering the page based on any settings. Same site attribute is just a part of the logic in the specific web application that you are trying to load, exactly how that affect the result page would depend on the web application/page. For example, typically the web server would redirect you to a log in page if an authentication cookie does not exist, it could very well choose to send a blank page to you in this case too. It could also be running some JavaScript code that dynamically loads contents and ran into an error while accessing cookies. The key here is, if the browser engine is working properly, then ultimately it's the web application/web page that decided to serve the browser engine an empty page, it's not the browser engine got a valid non-empty page but decide to render it empty.
Of course the other possiblity is the browser engine is not working properly. In that case we would need a test project in order to investigate further.
Thanks!

i can provide a test project, but unfortunately, the url that needs to be hosted is a "one and done" type url and they are only good for 10 minutes.
We have been using the version of the eo webbrowser from 6/2017. that is the one that renders an empty page. I downloaded the current version as a trial but i did not get the license key. "Part" of the page will render but not all of it. I'm not sure if that is because of the license key or if it is a java script error or what.
I am really scratching my head on this. I can give you the test project and then if you are available, i can generate a url that would be good for 10 minutes....but you can only try it once. not sure if that is feasible for you.

Hi,
You would have to have something longer than 10 minutes first in order for us to investigate. Even if we were super fast at debugging, there is no way we can find the root cause for you in 10 minutes.
You do need to update to the latest version first. Not only all the debug/fix will be done on the latest version, but also your 2017 license key won't qualify you for free support (we only provide free support for one year). As to license, make sure you DO NOT apply your 2017 license key when you test the new version. If you do not provide a license key, it will automatically enters trial mode and you can try everything. It appears that this is already the case for you since otherwise you would receive an invalid license exception. So in your case, only "part" of the page is rendered is due to something else, not due to the license.
Thanks!
