Sorry for the delay on this reply. You want to extract the contents including all of the folders in the phpbb3 directory to the forum folder you made. Your path /home/mydomaincom/public_html/forum is correct. The forums index.php file should be in that directory. Then you can run the installer by going to /home/mydomaincom/public_html/forum/install/ in your browser.

You are welcome. I hope your bike ride was enjoyable. Ask here if you have any more questions.

Something I forgot to mention earlier is it’s a good idea to disable registrations in the phpBB ACP and let WordPress handle them. Of course with the user integration turned on. I like to use the paid memberships pro plugin for that but any registration plugin will do, even the default reg form is fine.

I also went into the phpBB code and redirected all registration links to the WordPress register form. I eliminated a lot of the notorious phpBB user spam by doing this.

Have a great day!

Here is a breakdown on how I installed.

1) Setup a fresh WordPress install for 4.1.1
2) Install and activate WP-UNITED plugin for wordpress
3) Create a new folder in the WordPress root called forum
4) Extract phpbb 3.0.12 to the forum folder you just made.
5) Install phpbb https://localhost/wordpress/forum/install/ (remember to delete the install folder when its complete)
6) Download and Install Automod for 3.0.x (Extract contents of root folder to the /forum/ directory where you installed phpbb. Overwrite all files)
7) Install Automod. Once again run the installer found at https://localhost/wordpress/forum/install/
8) Once auto mod is installed purge forum cache and open the automod tab in the phpbb ACP and download the phpbb mod https://spiritloveforum.com/kingsblend/wp-united-release-phpbb.zip upload the zip and install the mod.
9) After the wp-united automod upload install there is a link you MUST click to install the database aspect of wp-united. It will be in a green box during the automod install. You will get errors if you are on conflicting versions of phpbb and wordpress. You will have to force install. The default options will work. The mod is written for 3.0.10 but it will work for 3.0.12 and even 3.0.13 but I personally have not tested version 3.13
10) Once successful go to the wordpress dashboard and run the wp-united setup.
11) You must point to the config file in the /forum/ root for phpbb.
12) Now you should be setup select the options you wish to use for the bridge.
13) When it comes to theme integration I found this mod WILL NOT work for a full CSS integration. YOU MUST TURN OFF THE SLIDER FOR THIS. All the way to the left.
14) You can play around with the way the theme integrates but I found that a statically cached simple header and footer works.
15) I spent a lot of time changing the wordpress twentythirteen theme and the prosilver theme to fit my needs color wise and element wise so some tweaking is involved. Google Chromes inspect element feature is a LIFESAVER.

Also keep in mind I have only had this work with the phpbb prosilver theme. Subsilver breaks on theme integration I believe. Plus no one really uses that theme anymore. I can do some support here I suppose for basic questions. Ask away. I hope this helps someone. Enjoy!
