### Error Code 5: Email Failed to Send
**Why does this happen?**  
This happens when there is a problem with your SMTP server, PDF generation, or Captcha settings.

## ${color}[#314AF3](Solution)

### Step 1 | Google Captcha
* a. Access the **Global Settings** menu of **Stylish Cost Calculator**.
* b. Do you have Google's Captcha settings turned on? If yes, try turning it off.

**✅ Did it fix the problem?**  
If yes, then you have a problem with your Google Captcha settings. Verify you have the correct API keys.  

**⭕ Still have a problem?**  
Then, Google Captcha is not the problem, please proceed to step 2.

### Step 2 | PDF Generator
* Let's test if the problem is the PDF Generator by trying to download a PDF in the backend.
* a. Access your calculator in the dashboard (backend).
* b. Click the **Detailed List** button.
* c. Click the **Save** icon.

**⭕ Did it fail?**  
Then, try removing your banner and logo in the global settings menu. If that fixed it, re-add it back. It could be a missing file, corrupted file, or wrong image format.  

**✅ Did it work?**  
If yes, then the problem is not your PDF Generator. Proceed to step 3.

### Step 3 | GD Library
In order for **Stylish Cost Calculator** to work, it needs the GD PHP Library.
* a. Click Diagnostic in the **Stylish Cost Calculator** menu.
* b. Check if you have a green button under the GD library.

**⭕ Is it red?**  
Then, talk to your hosting company about how to install the GD Library.  

**✅ Is it green?**  
Then, the problem is not the GD library, please proceed to step 4.
---
### Step 4 | SMTP Settings
In most cases for **Stylish Cost Calculator** to work, you need to have a proper SMTP plugin that routes the emails via your own SMTP server.
* a. Access the WP SMTP plugin.
* b. Click **Settings**.
* c. Click **Email Test**.
* d. Send yourself an email test.

**⭕ Did it fail?**  
Then you have to fix your SMTP setting. It may be the wrong port or credentials.  

**✅ Did it work?**  
Then, the problem is something other than the four things above. Please submit a trouble ticket and advise us of all the troubleshooting steps that you have taken.
