After applying update 5 for CF2021 to one of our production servers the CFAdmin throws this error upon login: "Error invoking CFC /CFIDE/administrator/updates/download.cfc" Everything SEEMS to be running fine, except the Packages page loads empty. Looking at errors within FusionReactor I can see the error under the hood is: "javax.servlet.ServletException: java.lang.NoSuchMethodError: coldfusion.runtime.CFPage.XmlSearch(Lcoldfusion/xml/XmlNodeList;Ljava/lang/String;)Ljava/lang/Object;" I've seen the SO thread and I've seen a thread on here about the XML updates. This instance does have the recommended jvm argument and the classes have been cleared and rebuilt. I even manually uninstalled/reinstalled the update. I've updated about 10 other instances to update 5 with zero issues and it seems to only be impacting CFAdmin. Has anyone else seen this behavior?

@sandip_halder was able to work with me get this resolved. it seems that somehow the administrator package did not get updated, so there was a disconnect. manually forcing the install of packages and restarting the instance resolved the issue

Wow! I just attempted to update to 5 yesterday and received this same error. Reading all this was helpful! Thank you!
