Why Is It Better to use Magento 2 Blog Extension Than Integration With WordPress, Joomla, Drupal

In Magento 1 merchants commonly used Magento for an online store and some other CMS, e.g. WordPress, Joomla or Drupal for blogging, then installed different tools to make the integration between these systems.

For Magento 2 there is the Blog extension that allows you to have a store and a blog in one place. Here are the advantages of using Magento 2 Blog Module over other blogging platforms or integration modules:

1. Security

Magento is one of the safest frameworks. Safety is the top priority for any successful business. And it's known that WordPress and other blogging CMS are not famous for their security, especially when being installed with additional modules. That's why using Magento extension which expands Magento itself is better. M2 Blog extension has passed over all verifications on Magento Marketplace, including security and it is safe to use.

Fix: Blog Search Does Not Work

If your Magento 2 Blog search does not work, most likely the issue is in your theme that overrides original blog templates and layout files.

Try the next steps:

1. Make sure that you have the latest Magento 2 Blog module version.

2. Try temporary remove Blog layout XML files and template PHTML files from your theme one by one and run static content deploy. Once find the file that brings the issue, pay attention to it.

3. Check if a blog search button in the sidebar has the attribute "disabled", if yes then it is disabled (not active), and this may be a root of the issue. In this case, find a code which makes it disabled. The disabled attribute can be added directly via .phtml file in your theme or with some JavaScript. If you cannot find it, then you can insert this JS script to undisable the button:

<script>
require(['jquery', 'domReady!'], function($) {
    setInterval(function(){
        $('#blog_search_mini_form .action.search').removeAttr('disabled');
    }, 2000);
});
</script>
