UPDATE:
I'm using the Bliss template... so I edited the file ../templates/Bliss/chat_send.tpl
I changed:
<input type="text" autocomplete="off" name="chat_box" id="chat_box" size="30" maxlength="150" onkeypress="parent....
to:
<input type="text" autocomplete="off" name="chat_box" id="chat_box" size="30" maxlength="500" onkeypress="parent....
But it didn't work like I wanted. It will now let the operator and end-user type up to 500 characters, BUT...
1) It pops up a message saying the message is too long and will be trucated. (It truncates down to 300 characters)
2) It displays the new truncated 300 char message to the display of the person who typed it, but not to the other user
Nothing over 150 char seems to get written to the database and shown to the other person.
Please help... I have to get this thing running this weekend.
