There are several known sorts of reasons the screen might be blank:
1)
Cause: You're running a new PHP 5 release with an old WSN release. PHP 5 releases tend to break things so when you update your PHP version you may need to update your WSN version.
Solution: Upgrade to the latest version of the script to get the latest PHP 5 compatibility.
2)
Cause: You've just upgraded to a new version, but fields couldn't be added properly, and each category has become a blank page.
Solution: You probably have a broken mysql table index. Use phpmyadmin to look at the structure of your wsnarticles_links table. At the bottom is a list of indexes. If 'wsnindex' lists the same field twice, delete it. Then re-run upgrade.php.
3)
Cause: You turned on gzip compression in your admin panel without reading the manual entry.
Solution: Read http://scripts.webmastersite.net/wsnlinks/wsnmanu...
4)
Cause: Miscellaneous filesystem problems.
Solution: Reinstall to a new directory, making sure that you don't chmod anything except config.php until you've verified that you can view the site. If it works, you can then delete your old directory and rename the new one to it.
5)
Cause: You've disabled the display of errors. If you set debug mode to "supress all errors" the screen won't give you any clue of what went wrong.
Solution: Set the debug mode back to normal (use phpmyadmin to update debug in the settings table if you can't get to your admin panel). You will then be able to get an idea of what the problem is.
6)
Cause: You have the mod_rewrite .htaccess file and mod_rewrite isn't functioning correctly (or needs .htaccess modification) on your server.
Solution: Delete the .htaccess file, and turn off url rewriting in your admin panel if it's on. Then see the manual entry on url rewriting and/or contact your web host to determine if you can get that feature working again.
7)
Cause: Check if you can see your site by going to index.php?debug=1 ... if you can, it would seem that somehow output caching has ceased working in your PHP installation.
Solution: Ask your web host.
