Frequently Asked Questions

  • Is this child theme responsive? 
    Yes the theme is fully responsive
  • What is unique in this child theme?
    We have completely refreshed the look from the default Clipper layout. The Flatter child theme layout is based on Flat Design, which practically means there are very few images used in the design, improving the performance on all devices. With the use of mobile phones for browsing websites ever increasing, the real icing on the cake comes in the form of the option to prevent each widget from displaying on mobile devices (not hiding it using CSS), which will keep the pages tidy and improve performance further
  • Do you plan to create more child themes along the same lines?
    Yes, we subsequently launched FlatPress for ClassiPressFlatPage for Vantage, and FlatRoller for JobRoller, so the customers can have consistent branding if they use more than one theme from AppThemes
  • How do I show more then 10 coupons on the homepage?
    Open SettingsReading page in your WP admin back end, and you can change the “Blog pages show at most” setting from 10 to another number, and that should reflect on your site.
  • How do I show grid view on the stores page?
    Open taxonomy-stores.php file in wp-content/themes/flatter/ folder and find replace all instances of the following code:
    <div class="box-holder">
    <div class="box-holder grid">
  • How do I update the theme manually?
    To update, you should extract the Zip file locally and overwrite the contents in the /wp-contents/themes/flatter/ folder. I always rename the new version folder from flatter to flatter-new on my computer and once it’s uploaded on the server, just quickly rename the older version from flatter to flatter-old and the new one from flatter-new back to flatter. This way the switching takes the minimum amount of time and also you can roll back to the older version just in case the new one doesn’t work out.


  • Extract zip in the /wp-content/themes/ directory.
  • Activate the theme through the ‘Appearance’ menu in WordPress.
  • Go to Clipper → Flatter Settings → General to setup overall site options.
  • Go to Clipper → Flatter Settings → Homepage to setup options for homepage including “grid view”, “tabbed view” and “full width”.

Support Policy

From February 2015, support will only be available via email from our email address .

Before you email us, please make sure you have browsed/searched through product forum for the answer to your question, and have read through the Support FAQs below:

Support FAQs

  • What kind of support is offered with a purchased product?
    Your product purchase includes one year of access to premium support via email and one year or free updates. Beyond that, you will need to renew your subscription year on year for around 30% of the product price. Support covers issues such as bug fixes (if any) under normal operation, how to use basic product features, very basic WordPress help, and help with very basic theme customisaton. If you need more advanced modifications please consider hiring a developer to do it for you.
  • Will you provide help with small modifications?
    If you need to do small modifications, you may get help from us as long as they are reasonable in number and nature. If you have a lot of such modifications, please consider paid developer help.
  • What kind of help would be unreasonable to ask?
    This is not an easy question to answer. We are here to ensure that the product you purchased works as intended by us and serves its purpose on your website. That means if it doesn’t work for you, we can step in and help you with it. However, it is when there are no issues with the functioning of the product and all you want is help with modification, that demands start getting unreasonable.
    As mentioned before, we don’t mind helping with modifications, but we also expect you to have tried everything to do it yourself. In other words, we expect you to have tried all the settings in your theme, ensured that the issue relates to the product in question, searched through legacy product support forum, and looked around on Google for the answer to your questions before approaching us. Please bear in mind that one theme, one child theme and a few plugins can get you only so far, and you will probably need to make changes to the code of your website to add functionality, change design and personalise it. In case of too many modifications, we will politely ask you to seek paid help.
  • I am using one of your child themes. I am having an issue with it.
    Please make sure the issue is really with the child theme by activating the parent theme and checking if the problem gets solved. Also please make sure you have tested all the settings in parent theme and child theme, sometimes the answer is right in there! Send us an email if the issue still persists.
  • I am using one of your child themes. I need help with customisation.
    As a pre-requisite, you are going to need a basic understanding of HTML & CSS to start customising the layout and style of your theme. To dig deeper PHP knowledge, specifically to WordPress, will help as well. The WordPress Codex is a great place to start learning. For CSS changes related to text colour, background colour, fonts, etc, please consider using the Firebug extension. A simple Google search returns many good text/video tutorials.
  • Do you offer paid WordPress development services?
    Yes we do depending on our work schedule. You can always run your requirements by us via email.

        • author

          You can change that text on footer.php
          and about renaming the folder of clipper, yes you can do it, but make sure you change the flatter/style.css , on the top lines you find this one
          template: clipper;
          change that clipper too.
          one more thing, you will not receive update of clipper automatically.
