Posting problems

i always post a new topic something and the it says that the maximum character is 255
and i only put like 40 characters and i keep getting the message that i put over 255 characters

What sentence did you add?

what do you mean by what sentence

What are the 40 characters you are trying to put in the title?

Also have you made sure that you have not decresed the amount of characters maximum? I dont know this off the top of my head, and I am not able to access my panel from this computer.
