If you are about to upgrade your message board, read this warning . Upgrade Warning * When you click 'Install', your existing program files will be replaced with their updated revision. If you have made modifications to these files, they will be lost and will have to be merged -again- into the new files. * One file, hacks.php, can be backed up now and restored after upgrade. Properly written modifications should store their code in this file, eliminating the need to merge that code after upgrade. * Your first skin directory, the one stored under templates/1/, will also be replaced. We recommend that you always use a copy of this skin as your default skin. * Your configuration will not be lost. If you need to make a backup now, do not click 'Install'; instead, perform a backup, then come back here! Please read these notes about problems uncompressing files . About Files Problems It is possible that, after clicking 'Install', the next page will display a red error code: Most PHP programs come with a semi-automated install process: you have to copy all the program's files to your web server before running a configuration script - if any. nextBBS is very easy to install on 'friendly' web servers: just upload two files, run the installer and let it guide you through its configuration wizard. Unfortunately, there are about as many possible configurations as there are web servers; as a result, the installer may be unable to properly copy your new files. If this happens, you will need to follow the inistructions provided on the next page; these instructions allow you to revert to a 'traditional' setup process. >>> Install

anyone can help what to do now????
