Well, I’m working withEE2.1.1 (latest build) Safari 5.0 (OSX) and got no problems to login. Yesterday I installed MSM (2.0) and now it’s working with 3 different sites.
Today I visited a client and tried to login (Firefox and IE7) but it didn’t work. On my way back home I tried to login with my iPhone 4 and it didn’t work.
Now I’m home and I can login with my Safari 5.0 browser on my iMac. But all other browsers on my iMac didn’t work.
No error messages or anything else was shown. I type my username/password in and nothing happens.
My webhost is EngineHosting. Is there a MSM bug? On other sites without MSM I have no problems. Please fix it soon, these are my live-sites and I need to login.
