Troubleshooting Salesforce Summer 25 release and Visualforce URL deprecation

What's happening?

Salesforce has rolled out the Summer '25 release across all Salesforce organizations, which includes the enforcement of a hard cutoff for all legacy Visualforce domains. As a result, any URLs referencing the deprecated domains are no longer functional. 

This change has impacted several Simpplr features, including Single Sign-On (SSO), the App Launcher, Remote Site Settings, and any embedded URLs used within content or tiles.

Here is the SF article with release notes and information regarding this change - Update References to Legacy Host Names (Release Update)
 

Customers can verify the specific date their Salesforce instance will be upgraded to the Spring '26 release by referencing their instance version through the Salesforce Trust site.

How do I fix it? 

1. Navigate to your Salesforce instance that Simpplr is built on, then go to Setup > My Domain.
2. Click Edit under the Redirections section.
3. Select the checkbox labeled Redirect legacy (non-enhanced) My Domain hostnames and ensure Maintain legacy redirections during the Winter ’26 upgrade is also checked.

Enabling these settings will temporarily restore redirection functionality for legacy Visualforce URLs, and Simpplr will work seamlessly. Please note that this is a short-term solution and will remain effective only until the Spring '26 release, which begins rollout on February 26, 2026.

Prepare for the end of redirections for legacy Salesforce URLs email

Beginning with the Salesforce Spring ’26 release, which will start rolling out on February 26, URL redirection will no longer be supported. All URLs must be updated to the new format to ensure proper functionality.To mitigate any risk of URLs not working please do the following: 

Search for all instances of URLs with “visual.force.com” by running these queries:

• For intranet Pages: 

Select id, Simpplr__title__c, CreatedDate, Simpplr__Text_Json__c, Simpplr__Text_Main_Continued_Json__c, Simpplr__Text_Main_Json__c, Simpplr__Text_Intro__c, Simpplr__Text_Main_Continued__c, Simpplr__Text_Main__c from Simpplr__Simpplr_Content__c where Simpplr__Title__c != '' and Simpplr__Is_Unpublished__c = false and Simpplr__Is_Archived__c = false and Simpplr__Is_Deleted__c = false order by CreatedDate desc

• For Tiles: 

Select Id, Simpplr__Data__c from Simpplr__Tiles_Config__c

Once you find the location of each legacy URL, please update the content inside the page or tile.

If you’re not sure how to find all pages with legacy URLs please submita Support ticket and grant admin access to your instance. The Simpplr Support team will handle the updating of legacy URLs in your instance.
