Theme Installation

There are 2 ways to install a Wordpress theme.

Installing Theme From the WordPress Dashboard

Installing a WordPress theme is super easy, you’ll see our video guide:

- Step 1: Navigate to Appearance → Themes in your WordPress admin dashboard.

- Step 2: Click the Add New button at the top of the page and go for the Upload option.

- Step 3: Choose inogen_theme.zip then click Install

- Step 4: Wait while the theme is uploaded and installed then activate the theme.

Install theme via FTP

Many users are on shared hosting with low upload limits, and in such situations the Inogen theme is often too large to install through Wordpress. We suggest you should upload it via FTP.

If you don't know how to use FTP visit this link for information: http://codex.wordpress.org/FTP_Clients . You will need to first uncompress the PACKAGE-theme.zip file you have found in the master zip downloaded from Themeforest. This zip uncompresses into a normal folder. This unzipped folder is all you need to transfer via ftp and if you open it, you will see all sorts of folders and css and php files which together contain all the theme coding.   

Using the FTP program transfer this folder which contains the above files to the Wordpress installation theme root directory: /wp-content/themes.

Do not upload any of the other files or folders such as licensing or resource or documentation. Uploading any of the other folders may cause problems resulting in the theme not working properly. Learn from Wordpress Official Documentation about installing theme with FTP client or with cPanel: http://codex.wordpress.org/Using_Themes

Activate Inogen as default theme

After completing the upload, activate the theme as per activating any other theme.

Go to your Dashboard >> Appearance >> Themes >> Activate Inogen template

Follow the instruction from the image below:

Known problems when installing the theme

a. The “Broken theme and/or stylesheets missing” error is most common when you install or activate a new theme.

If you get an error saying that the stylesheet is missing, then you have uploaded the wrong folder. Please check that you are uploading the inogen_theme.zip within the Theme Files folder. You have to unzip the package file that you download from Themeforest to find this.

b. Problems with uploading via WP admin panel due Upload limit.

You may check your file upload limit on Your Media Uploader page in WordPress. Depending upon the web hosting company and the conditions of the service they provide it may vary. The most common is about 8 MB which is more or less enough. But uploading some media files like audio and video may become a problem with for example 2 MB upload limit.
We decided to share some tips about how to extend your maximum file upload size in WordPress:

1. Through functions.php file:

You may add the below mentioned code in the functions.php file of your theme

@ini_set( 'upload_max_size' , '64M' );

@ini_set( 'post_max_size', '64M');

@ini_set( 'max_execution_time', '300' );

2. Through PHP.INI file:

If you cannot see the php.ini file in your directory create the new one with below mentioned code and upload it to your root folder on your web server.

If you can see the php.ini file then change parameters or add :

upload_max_filesize = 64M

post_max_size = 64M

max_execution_time = 300

In case that tip does not work with 64MB, try it with 10MB.

3. Through .htaccess method

You may try modifying the existing .htaccess file in the root directory or creating a new one.

Add the following code in the existing or new .htacess file:

php_value upload_max_filesize 64M

php_value post_max_size 64M

php_value max_execution_time 300

php_value max_input_time 300

You can reset all of the setting for the each page on our custom panel by clicking “Reset” button on the bottom.

2. How to create Child Theme

What is a Child Theme?
A child theme is a theme that inherits the functionality of another theme, called the parent theme. Child themes allow you to modify, or add to the functionality of that parent theme. A child theme is the best, safest, and easiest way to modify an existing theme, whether you want to make a few tiny changes or extensive changes. Instead of modifying the theme files directly, you can create a child theme and override within.

Why use a Child Theme?

if you modify an existing theme and it is updated, your changes will be lost. With a child theme, you can update the parent theme (which might be important for security or functionality) and still keep your changes. It’s a great way to get started if you are just learning WordPress theme development.
