It is based on phpBB 3.0.11. I checked the Google Analytics report. There are about 20% users using cellphone or iPad.
To accommodate these users, I installed a mobile style on it and added the Mobile device detection facilitate.
There are 4 steps to install it. Very easy.
Download the Style package and unzip it.
Unzip it and the folder structure looks like below.
Upload all files unziped into the Styles folder on server.
In style directory, subdirectory "contrib", in that directory you will find file "mobile.php" (art_mobile_blue/contrib/mobile.php). Copy it to the forum to directory "includes".
Open includes/session.php, find this:
// Call phpbb_user_session_handler() in case external application want to "bend" some variables or replace classes...
// After calling it we continue script execution...
and add before it:
// Mod: phpBB Mobile start
include_once($phpbb_root_path . 'includes/mobile.' . $phpEx);
phpbb_mobile::setup('art_mobile_blue'); // Change first parameter to correct directory name of mobile style
// Mod: phpBB Mobile end
The detecting function is working automatically. But if you want, you still can switch it back to the full style manually.
The above how-to is based on the style Mobile & SEO Blue / orange version 3.2 for phpBB 3.0.8 - 3.0.11
