Line breaks are spaces, as if you hit enter. There will be a space between every line in what is pasted in notepad, which is why it went to word in the first place. Early on (my third week of creating the tutorial) I ran into a major snag and had to revert back to my latest backup. It was on notepad at the time and after my jaw dropped after posting my backup. I soon found out (was told) about notepads line break issue.
Anywho, to answer your other question, I just posted the same in a different forum and it worked fine so the problem isn't with the code since the other forum is phpbb2 and my forum is bb3.
One thing I did a couple minutes ago was made a few changes that didn't seem to take effect so after reading, found that I had to clear my cache. After I read that I tried again as in the link you posted and found something strange.
If I do as mentioned and set my maximum character count to 60,000 I will get an error saying my post is 198,450 charcters (I told you it was huge
. So I decided to copy 50,000 characters worth and it worked. Having seen that I went back to the control panel and raised my max count to 200,000 and once I again I seen the same error above "Your message contains too few characters".
I could go through the process of making this a 4 post, topic but kind of defeats the whole purpose. This post was legendary haha. But seriously, something is wrong with bb3 if I can post it just fine in other forums. Why the 60,000 limit on bb3? There must be something else that is capping it, but I don't see any reason why I can't raise it to 200k.
Atleast I got somewhere tonight, tomorrow (your today) is another day and look forward to hopefully finding a fix, rather than just a work-around.
