Many WordPress users install the wpDiscuz plugin expecting a modern comment system, but after installation they still see the default WordPress comment form. This issue is very common when using block-based themes such as VisualBlog or other Gutenberg powered themes.
If you recently installed wpDiscuz and your site still shows the standard “Leave a Reply” form with fields for Name, Email, and Website, then the plugin is not replacing the theme’s comment template correctly.
In this guide, you will learn how to properly enable wpDiscuz, connect it with your theme, and fix the common conflict that happens with block themes. The tutorial also explains how to stop spam comments and protect your blog from bot attacks.
Understanding the Problem
WordPress themes control how comments appear on posts. Traditionally, themes use a PHP function called:
comments_template()
This function loads the comment form and allows plugins like wpDiscuz to replace the default WordPress comment system.
However, modern block themes use the Gutenberg Comments Block, which renders comments differently. Instead of loading comments through the PHP template, the theme displays comments using block elements such as:
Comments
Post Comments
Comment Form
Comment Query Loop
Because of this change, wpDiscuz cannot automatically replace the comment form.
This is why you may see the default comment form even though wpDiscuz is installed and configured correctly.
Step 1: Install and Activate wpDiscuz
First ensure the plugin is properly installed.
Go to the WordPress dashboard.
Navigate to:
Plugins → Add New
Search for:
wpDiscuz
Install and activate the plugin.
Once activated, a new menu will appear in the dashboard called wpDiscuz.
Step 2: Verify wpDiscuz Is Enabled for Posts
Now make sure the comment form is attached to blog posts.
Go to:
wpDiscuz → Forms
Open the form called:
Default Form
Scroll down until you see:
Display comment form for post types
Make sure the following option is selected:
post
If this option is not enabled, wpDiscuz will never appear on blog posts.
Save the form after confirming.
Step 3: Confirm WordPress Comments Are Enabled
WordPress itself must allow comments.
Go to:
Settings → Discussion
Enable:
Allow people to submit comments on new posts
Next, edit one of your posts.
On the right sidebar open the Discussion settings and confirm:
Allow Comments
If this option is disabled, no comment system will appear, including wpDiscuz.
Step 4: Identify Block Theme Comment Conflict
If everything is configured correctly but the default WordPress comment form still appears, the problem is usually caused by a block theme.
Block themes use the Site Editor.
You can confirm this by checking if your dashboard has:
Appearance → Editor
If you see this option, your theme is a block theme.
This means the comment system is controlled by blocks instead of PHP templates.
Step 5: Fix Comments in the Site Editor
To allow wpDiscuz to work properly, you must remove the Gutenberg comment block.
Go to:
Appearance → Editor
Click:
Templates
Then open the template called:
Single
or
Single Post
This template controls how individual blog posts appear.
Scroll down until you find the comment section.
You will likely see a block group containing elements such as:
Comments
Post Comments
Comment Form
Comment Title
Select the comments block.
Open the options menu and remove the block.
Step 6: Insert wpDiscuz Instead of the Block
After removing the comment block, you must add the wpDiscuz comment area.
Click:
Add Block
Search for:
Shortcode
Insert a shortcode block and paste:
[wpdiscuz]
Save the template.
Now open one of your blog posts on the front end and refresh the page.
You should now see the wpDiscuz comment interface instead of the default WordPress comment form.
Step 7: Clear Cache After Changes
If your site uses caching, the old comment form may still appear.
Clear the following:
Website cache plugin
Cloudflare cache (if used)
Browser cache
Then refresh the page.
Step 8: Stop Spam Comment Attacks
Many websites receive automated spam comments from bots. These comments often contain links to adult sites, gambling sites, or fake services.
If you saw comments like:
buy cannabis online
adult content links
porn site promotions
then your website is being targeted by automated spam bots.
You must configure comment protection.
Enable Google reCAPTCHA
Go to:
wpDiscuz → Settings → Google reCAPTCHA
Create reCAPTCHA keys from Google and enable version 3.
This adds invisible bot protection to the comment form.
Enable Comment Moderation
Go to:
wpDiscuz → Settings → Comment Moderation
Enable the following options:
Comment must be manually approved
Hold comment if it contains links
This prevents spam comments from appearing publicly.
Close Comments on Old Posts
Older posts are the most common target for spam bots.
Go to:
Settings → Discussion
Enable:
Automatically close comments on posts older than 30 days
This greatly reduces spam.
Disable Website Field to Reduce Spam
Many spam bots use the website field to insert links.
Go to:
wpDiscuz → Comment Form Settings
Disable or hide the website field.
This removes a major spam entry point.
Additional Security Recommendations
To further protect your site from spam attacks you can also:
Install a firewall plugin such as Wordfence.
Enable login attempt limits.
Use Cloudflare bot protection.
Block suspicious countries if spam traffic originates from them.
These measures help protect your entire website, not just comments.
Why wpDiscuz Is Better Than Default WordPress Comments
The default WordPress comment system has not changed much in years. It lacks features that modern blogs need.
wpDiscuz improves engagement by providing:
Real-time commenting
Modern user interface
AJAX loading comments
Inline feedback options
Comment voting and reactions
Subscription notifications
It also integrates with spam protection tools to reduce bot comments.
Common Mistakes When Setting Up wpDiscuz
Many users make these mistakes during setup.
They enable wpDiscuz but forget to attach the form to post types.
They use a block theme where comments are rendered using blocks.
They disable comments in WordPress discussion settings.
They forget to clear cache after installing the plugin.
Once these issues are fixed, wpDiscuz works correctly.
Final Thoughts
If you installed wpDiscuz but still see the default WordPress comment form, the issue is usually related to block themes such as VisualBlog. These themes use Gutenberg comment blocks instead of the traditional WordPress comment template.
By removing the block-based comment system and inserting the wpDiscuz comment form instead, you can restore the plugin functionality and provide a much better commenting experience for your readers.
At the same time, it is essential to protect your site from spam comments by enabling moderation, reCAPTCHA, and other security measures.
Once configured correctly, wpDiscuz can transform your blog’s comment section into an interactive and spam-resistant discussion area.
