Windows Upgrade Help and more

This is an example post in your phpBB3 installation. Everything seems to be working. You may delete this post if you like and continue to set up your board. During the installation process your first category and your first forum are assigned an appropriate set of permissions for the predefined usergroups administrators, bots, global moderators, guests, registered users and registered COPPA users. If you also choose to delete your first category and your first forum, do not forget to assign permissions for all these usergroups for all new categories and forums you create. It is recommended to rename your first category and your first forum and copy permissions from these while creating new categories and forums. Have fun!

Glad I'm not alone. Same issue on my PC.

Yeah, Did you try clearing your browser cache after the install?

Same here. Agreed, and also double-check that file permissions are set correctly on the server. Good luck!

You could also try clearing your browser cache or using a different browser to see if it loads properly.

+1 Yeah, clearing the cache usually does the trick. Also, double-check that you're actually logged in, as that can sometimes cause a blank page.

If it's still blank, have you tried disabling any recently installed mods?

You could also check if your database user has the correct permissions to write to the tables.

+1 Another option is to verify that the file permissions on your server allow phpBB to write to its config files.

Yeah, Also, have you checked if the database connection details in your config.php are correct?
