Captiveportal using the GPP WebUI is working with Internet Explorer v.8.0.7600.16385 and Mozilla Firefox v.9.0.1 the functions are fine. However, in Internet Explorer v.9.0.8112.16421 – cannot create guest accounts via GPP. IEv9 refreshes every sec making it impossible to create a user, modify, and even logout. Has anyone else had this problem, or similar issue?
