It worked for me - all of two days. Now it's broken again...

I must have missed those two days.  I keep clearing cache but it still wants login every time.   

Same here. Worked all weekend, now broke again.

I can't even get 123rf to open anymore. The last few days I get a message that 'this website has a 'omleidingslus' (dutch). Translated it has something to do with redirected. I can't get into the site on my computer. On my Ipad I can.

I'll be happy to supply the information, but it stopped working for everyone, then it got fixed for everyone, then it stopped working for everyone. This isn't something specific to us or happening on our end. Someone in your I.T. dept, changed something, then changed it again, then changed it a 3rd time.
Also, as I have referenced before (someone could dig thru forum archives if they have the energy, this happens about once a year, with the same type response from 123 and eventually, after a lot of this back and forth, it gets fixed. I've been in I.T. for 30 years and I can almost guarantee one thing. Someone in your I.T. dept, knows what the problem is.

Now it is even worse.
I must login two times with same password, because first time "password is wrong".
123rf, do You need a help?

No, it was fixed for a couple of days, then they broke it again. Stopped caring. Not going to clear my cache or delete my cookies. Not going to tell them what browser I'm using. Same one I've been using for years. We didn't break it, they did. If they cared they could fix it. They don't. Used to go there many times a day, now it's once every few days. Clearly shifting the worth vs trouble equation the wrong way.
