thisisedie Posted January 31, 2011 Share Posted January 31, 2011 I have a simple guestbook set up. Even when I set the max post size to 6000000 (if you're wondering why Id allow that its cause I'm just using it as a private message board with one other person), after a certain amount of characters, it splits the post up into several messages and in place of the name of the poster, it's an IP. Any ideas why this is happening? Thanks. Quote Link to comment Share on other sites More sharing options...
ManiacDan Posted January 31, 2011 Share Posted January 31, 2011 You would have to...look at the code. Right now, all we can say is "the code is doing that." Quote Link to comment Share on other sites More sharing options...

ManiacDan Posted January 31, 2011 Share Posted January 31, 2011 Yeah, that's too much code (that's poorly written and indented) for me to slog through. If it's such an enormous problem, you can pay someone to do it. Something in that file causes the message to be split. Substr, preg_split, and a couple other functions will split a string. There's a constant called MAX_MESG_LEN, but it's set to 6000000 characters. I don't think that's what's biting you. Quote Link to comment Share on other sites More sharing options...
