A while ago set up a group forum using phpbb, overall phpbb3 is not bad even though it lacks of some popular features and you need some module for some popular features.
As more and more posts on our forum, I thought it might be a good idea to mark those posts with over a certain number of views. I checked and phpbb3 comes with popular topic based on posts, I want to have popular posts based on views.
Thanks and hates to http://startrekguide.com/mods, I found that some simple update of a few php files could get what I wanted:)) since I am so lazy and web stuff is just one of my hobbies. Why I hate? After I followed the instruction to update those files, I found the crazy warning about "Cannot modify header information - headers already sent by (output started t /includes/acp/acp_board.php:1)"!
What the heck? I changed file back (didn't save a copy since I was thinking those changes are so simple:(). Still same error pops up, double checked the space, commas, etc, still same error! It gets me frustrated, so I decided to change configure php file (even it says don't touch this file:( ) to uncomment the debug mode line to see what's really going on. Damn, even worse, whole phpbb forum is not running!
Thanks to the Internet search, sounds like I was having some encoding type issue, I edited those files in notepad to make sure same as UTF-8, but still same thing! Searched again, I was educated that I need to save as UTF-8 without BOM, the notepad doesn't have this option so called BOM:(
After downloaded notepad++ and edit the files and applied the changes according to http://startrekguide.com/mods, now I havd to say thanks. After that everything was working properly:)
I thought I should write this out and again LONG LIVE INTERNET SEARCH! (mostly google or baidu?:))
Byte order mark
From Wikipedia, the free encyclopedia
The byte order mark (BOM) is a Unicode character used to signal the endianness (byte order) of a text file or stream. It is encoded at U+FEFF byte order mark (BOM). BOM use is optional, and, if used, should appear at the start of the text stream. Beyond its specific use as a byte-order indicator, the BOM character may also indicate which of the several Unicode representations the text is encoded in.
