If you click on Yellowdig from within your course in your Learning Management System (LMS; i.e., Canvas, Blackboard, Sakai, Moodle, etc.) and see the Yellowdig homepage, a sign-in screen, or an error warning, this is frequently related to your browser or your network. Below are some things you can try to fix or figure out the problem.
Unless Yellowdig is unexpectedly down, which occurs fairly rarely (our uptime is >99%), most access problems are related to either the user's browser or links being misconfigured in your LMS. Yellowdig does not control course setup and can only fix problems in your LMS by contacting someone at your organization, so we ask for your patience in addressing some of these issues. If you continue to have problems after trying the steps below, please contact support (at the top-right of this window). If this is necessary, please try to tell us as much as you can about the steps you tried and the outcomes with any screenshots of the problem/error that might give us information about the specific error. The more information you provide us the quicker we will be able to identify the actual source of the problem so that we can get a solution.
Solution A - Try A Different Browser
Yellowdig works best with Chrome and Firefox and certain access issues are traceable to specific security-related policies of other browsers or just browser incompatibility. Many of these problems are solvable by simply using a different browser if you have that option. If you do this and you are prompted to allow cookies for your LMS or our website, allow them. Yellowdig needs cookies enabled to authenticate your account from your LMS sign-in. This also often solves other performance-related issues, especially if you are the only one in your class having the problem.
Solution B - Try An Incognito Browser Window and/or Clear Your Browser Cache
Sometimes data cached on your system can cause conflicts with new data being loaded. These issues can often be addressed by trying an incognito window or clearing your browser cache/history.
Solution C - Enable Cookies
Yellowdig (and any other LTI/LMS tool) requires access to 3rd party cookies to be enabled, but not all browsers are configured this way (or this can be changed by other software). Here's how to fix this in various browsers:
- Open Chrome Settings
- Click on "Show advanced settings..." at the bottom
- Under Privacy, click on "Content Settings"
- Ensure "Block third-party cookies and site data" is unchecked
- Click on "Done" to save
- Open Firefox Preferences
- Select Privacy
- Under History, select "Use custom settings for history"
- Ensure that "Accept third-party cookies" is set to Always
- Open Preferences
- Select the Privacy tab
- If you see the "Cookies and website data" section, ensure "Always allow" is selected
- If you see the "Block cookies and other website data" section, ensure "Never" is selected
Solution D - Disable Potentially Problematic Extensions
Some extensions cause conflicts with our system. Try disabling extensions or whitelisting Yellowdig therein. Common examples of such extensions are Ghostery and Ad Blocker Plus. We have seen some conflicts with grammar checking extensions as well. You would be able to confirm whether or not an extension is the culprit by first opening an incognito / private browsing window and launching Yellowdig therein. (Launching successfully into the corresponding Yellowdig Community would confirm the issue as being caused by an extension.)
This article should prove helpful if you're unsure how to open an incognito / private browsing window.
Solution E - Use a Mobile Phone to Ensure It Is Not Your Network Connection, Computer, or Your Specific Account
One way to determine if your network or your computer/browser might be the problem is to turn wifi off on your phone, access your LMS via a mobile browser using your cell phone data plan, and trying to launch into Yellowdig. If you can launch on your phone via a mobile connection it rules out the possibility that there is something wrong with your account or the link in the course and tells us for sure that something related to your specific browser/computer or your network is blocking your access.

If you do contact us, please let us know if you have tried this solution and what the result was.
