Hi all,
Kudos to the developer/s for creating this little gem!  I'm just about to start up a little business (with no money) and webim is both free and very useful.
I am however having some teething problems which are stopping me from appreciating it fully.  I've installed webim on my hosting account and placed a button in my opencart store. To test that it was working I initiated a chat from the store by clicking the button.  I heard the ting in the background and sure enough, a "visitor" was waiting to chat in the back-end.  
Unfortunately, when clicking the chat icon in the visitor section, the message window pops up but only displays the message 
old browser is used, please update it
I use firefox 25 chrome 31.#### and the latest version of epiphany.  All recieve the same message.
Something I haven't tried is to change the useragent to an older browser so I'll do that now.
As a side issue, how in the world do you clear active chat request that are just sitting there waiting?  I now have about 10 active (i know, I know... click the exit icon, right 

) but I now need to get rid of the ones already sitting there.
Thanks for the help in advance
Nick
