I have ISE 2.2.470 patch 16. I have tried the below scripts you suggested by no HTML/JAVA scripts seem to work in my ISE and the scripts seem to disappear after it is saved and you come back to the portal customization. HTML/Java are enabled for the portal customization is enabled and I am pasting it in under the html toggled and I have done it with the same spacing from the forum and with no spaces and I have tried it in both optional content spots and the instructional section of my devices migrated 1.2 port and a new test portal. I have been trying to work with TAC on this and they had no luck in ISE 2.2-2.4 and they experienced the same issues. They said that they do not really support this and I need to reach out in the forums. It just seems like java/html scripts are not responding at all. Do you have some basic script I can test with. Any assistance would be greatly appreciated.
