If these options are unavailable or disabled, contact the internal IT team to update browser policies. Some settings may appear under different labels in older versions of Microsoft Edge. #### Are these changes safe? These changes are safe: - **Applies only to OPUS** – The updates affect only `https://opus.tracelink.com/`. All other sites remain unchanged. - **Security protections remain active** – Antivirus, firewall, and Microsoft Defender SmartScreen continue to run. - **Improves performance** – Enhanced Security disables Just-In-Time (JIT) compilation, which can reduce performance for OPUS. - **Uses standard browser behavior** – This change restores Microsoft Edge to standard performance mode for a trusted site. ## User access [![Closed](/sites/default/files/tech_comms/admin/Skins/Default/Stylesheets/Images/transparent.gif)A user cannot log in](#)If the company owns Opus apps, users must go to opus.tracelink.com to log in to the OPUS or through an IdP that routes to opus.tracelink.com. Even if users only have access to Track & Track Services apps, they must access those apps through the OPUS. If a user still cannot log in to the OPUS, contact TraceLink Support. [![Closed](/sites/default/files/tech_comms/admin/Skins/Default/Stylesheets/Images/transparent.gif)I cannot see all the items in the menu ](#)Administrators assign roles that limit users' access to different functions. Depending on the role assigned, users might not see certain items in the main menu, network composer, or side menu. If you cannot see an item that you should see based on a role, verify that you are assigned the correct role. If you still cannot see the appropriate menu items, work with your System Administrator to ensure that you are assigned the correct roles and permissions.

These Links allow the Owner and their linked entities to collaborate and exchange data. In some instances, the Link fails to establish. If this occurs, System Administrators and Application Administrators can resubmit a failed Link with the same details that were previously added for the Link. The Link might fail due to the following reasons: - The TraceLink system is not reachable because master data is not accessible. - There is an issue importing bulk Links through a CSV file. - The identifier, which is used for a Partner or internal location to link an app or network, is not already added to the TraceLink Network. - An email address that the System Administrator or Application Administrator added when attempting to establish the Link that does not belong to a user on the TraceLink Network. ![](/sites/default/files/tech_comms/admin/Content/Resources/Images/global_images/note_tip_24x24.png)An email address is not required to establish a Link, but if one is provided for the user at the Partner or internal location, then it must already be in the TraceLink network. If the Link fails to establish, ensure that an identifier and the administrator email address is already added to the TraceLink Network. Then a System Administrator or Application Administrator can select the Retry Link icon to resubmit the failed Link. ## Help center [![Closed](/sites/default/files/tech_comms/admin/Skins/Default/Stylesheets/Images/transparent.gif)The API guideline I exported to Excel is incomplete](#)There is a known issue in the documentation where some API guidelines that are exported to Excel via the Download ![](/sites/default/files/tech_comms/admin/Content/Resources/Images/global_images/ensemble/download2.png) icon display only a portion of the entire guideline. This issue will be fixed in a future revision. [![Closed](/sites/default/files/tech_comms/admin/Skins/Default/Stylesheets/Images/transparent.gif)The API example I copied and pasted has invalid formatting](#)There is a known issue in the documentation where the example might have extra spaces or quotation marks added if copied through a Chromium-based browser (e.g. Google Chrome, Microsoft Edge). This issue will be fixed in a future revision. For now, if this problem results in a validation error, either: - Manually copy the example by highlighting the full text, right-clicking, and selecting Copy.or - Use a non-Chromium-based browser (e.g. Apple Safari) to copy the example. #### Table of contents ##### Related Content [ ![Related content](https://www.tracelink.com/sites/default/files/2024-09/warning-window.svg) ](/resources/tracelink-university/troubleshoot-problem-opus-solution-environment) ##### Troubleshoot a problem in OPUS Solution Environment This topic answers some common troubleshooting scenarios.
