Hi @John Gilbert Alcazar,
To avoid this issue, a SharePoint solution must be deployed and enabled on the SharePoint server. This operation explicitly enables pages to display in any iFrames. You could refer to following steps
- Download the Permissive XFrame Header SharePoint solution from: http://ventigrate.codeplex.com/releases/view/79825
- Unzip the PermissiveXFrameHeader DEPLOY.zip file. This operation displays three (3) folders. Each folder contains the Ventigrate.Shared.PermissiveXFrameHeader.wsp for either 2013 or 2016.
- SharePoint Management Shell: To start, right-click and run as administrator.
- Use the Add-SPSolution PowerShell command to add the downloaded wsp package (for the SharePoint version that you are running) to the SharePoint farm. (For more information, see Add-SPsolution on technet.microsoft.com.)
- Go to Central Admin > System Settings > Farm Management > Manage farm solutions. Select Ventigrate.Shared.PermissiveXFrameHeader.wsp and click Deploy solution.
- (When asked to deploy the solution) Now and OK: Select.
- Go to Central Admin > Application Management > Web Applications > Manage web applications and select the web application of your search center site.
- (In the ribbon) Manage Features: Click and activate the Permissive XFRAME-OPTIONS Header feature and click OK.
