You must have a really slow server.
Hereís what youíll need to do.
1. Open install/populate_db.php in a text editor, one that wonít insert formatting (like MS word) just a simple one (like notepad. I prefer NoteTab myself)
2. immediately after the <?php on the next line insert set_time_limit(300); making sure itís on a line by itself.
3. save the file and do the same for install/populate_db2.php (just in case)
4. re-install from the beginning.
This will extend the normal 30 seconds to 300 (or 5 minutes). If for some reason that isnít enough repeat the process with a higher number.
Youíll need to keep in mind that if the install is timing out, running the script may not work very well. I have a server set up on my home computer and that particular script (install/populate_db.php) takes about 4 to 5 seconds.
