Can't Send, Make or Accept/Refuse the offers Steam via Browser

What error does it give? 16? it usually sends if it is
,if sending

It does so to me too, but it actually still sends. Try sending an offer to a friend a couple times and ask him how much spam offers he got from you.

Well, I can't accept offers on Steam client, messaged support that I can't send or accept trade offers. Then they said that I've traded. I said yes, I've traded but in the trade window which I can only use when person is online and I can't send offers from inventory using Offer Trade button. In their next reply they told me same sh!t they said me last time and like that many times. I tried to be more clearer but they didn't understand (That time I thought if they had rocks instead of brain)

it works for me on browser, client always gives me problems.

I use Chrome too, and I hardly bother trying to send offers from my browser anymore since it's so buggy. Same with the market. Buying and selling I often have to keep logging out, back in and retrying. Kind of annoying since the client's awfully sluggish by comparison.

same here (firefox 30.0)

I have the same problem, but with the client. :D
