Hi everyone!
Just want to share with you guys that I have successfully installed XOOPS 2.2.3 Final on O/S: Fedora Core 4.

This is what I have done:
a. Installed Apache, PHP (php with MySQL enabled) using the installation CDs for FE 4.

b. <On> HTTPD and MySQL service in [Desktop]->[System Settings]->[Server Settings]->Services.

c. <Checked> Disable SELinux protection for httpd daemon. Restarted the PC.

d. Extract XOOPS 2.2.3 Final and copy [html] into var/www/html.

e. set chmod 777 for mainfile.php, [cache], [templates_c] and [uploads]

f. Run FireFox 1.0.4 and goto "localhost" for XOOPS installation.

Hope this can be of help to those out there.

Are you still working on Fedora 4.0?
