=/ I was struggling a bit CHMODDing to until I found out a short cut. Just because I like helping people, heres a guide on how to CHMOD.
1.) Download FileZilla, it's awsome and It's what I use.
2.) Upload your files
3.) Right click on your forums folder that contains everything and hit "File Attributes..."
4.) Change the value (755) to 777 and tick "Recurse into Sub Directories" and tick "Apply to all files and directories".
5.) Let it CHMOD automatically.
6.) After it's finished, load keygen.php by doing -
www.yourname.com/keygen.php
*If your keygen.php is in public_html, use the url above, if it's in /forums/ folder, it should be -
www.yourname.com/forums/keygen.php*
7.) Execute keygen.php
8.) After it has finished updating, copy the info down into a text.
9.) Go back to FileZilla and right click on the forums folder again and this time, set the value to 755 and tick "Apply to directories only".
10.) All your folders should be 755, now it's time for files, right click the forums folder again and type in 644. This time, tick "Apply to files only" and wait for all the files to be CHMODed 644.
Grats, you completed chmodding.
