No access to workpace after applying the patch EPM 11.1.2.3.500

After I successfully applied the patch EPM 11.1.2.3.500, I tried to login Workspace but I had a bad surprise:

“An error occurred processing the result from the server

URI: http://nomeserver:19000/workspace/modules/com/hyperion/bpm/web/desktop/Adf.jsp

Description: An invalid content type ‘text / plain’ was found INSTEAD of [text | Application] / xml ‘. “

I think this is a problem created by temporary files… then I did the following in the EPM Configurator utility:

– configure web server
– configure logical web address
– redeploy EPMA web

rebooted the server and started the services. I then could login to Workspace without any issues…
