Watermark PDF Issue

### Possible Solutions

#### 1. Adjust Watermark Layer in Plugin Settings
Some versions of the **WooCommerce PDF Invoices & Packing Slips** plugin have an option to adjust the watermark's layer or position. To check and adjust this:

– Go to your WordPress Admin Dashboard.
– Navigate to **WooCommerce > PDF Invoices > General**.
– Look for a section related to **Watermark Settings**.
– If there's an option for **Watermark Layer** or **Order**, set it to **Background** or a lower layer.
– Save changes and regenerate the PDF to see if the issue is resolved.

#### 2. Modify Custom Template (If Applicable)
If you're using a custom template for your PDF invoices, it might be necessary to adjust the positioning of the watermark. You can do this by editing the relevant template file.

– Go to `wp-content/uploads/woocommerce-pdf-invoices-packing-slips/templates/` (if you have custom templates).
– Open your template file (like `invoice.php`) and adjust the order of rendering for the watermark. Ensure it appears before other content is rendered.

#### 3. Add Custom CSS for PDF (DomPDF Custom Styles)
If the plugin uses **DomPDF** (a library you're already familiar with from your other projects), you can use CSS to push the watermark behind the text:

– Go to **WooCommerce > PDF Invoices > Custom Styles**.
– Add the following CSS:

.watermark {
    z-index: -1;
}

– Save and regenerate the invoice PDF to check if the watermark is now behind the content.

#### 4. Rollback to a Previous Version
If the above steps do not resolve the issue, you may consider temporarily downgrading the plugin to a previous stable version that worked correctly:

– Download an older version from the [WooCommerce PDF Invoices & Packing Slips plugin page](https://wordpress.org/plugins/woocommerce-pdf-invoices-packing-slips/advanced/).
– Deactivate and delete the current version (your settings should be preserved).
– Upload and install the previous version.
– Test the PDF generation again.

#### 5. Contact Plugin Support
If the issue persists, it could be a bug introduced in the latest version. In that case, contacting the plugin's support team would be advisable:

– Visit the [plugin's support forum](https://wordpress.org/support/plugin/woocommerce-pdf-invoices-packing-slips/) or the [official support page](https://www.wpovernight.com/support/).
– Describe your issue, and mention that it started after upgrading to version 5.0.5.

These steps should help you resolve or work around the issue with the watermark text showing above other content in the PDF.

### Steps to Fix the Watermark Issue

#### 1. Modify Watermark Settings in the Plugin
The **WooCommerce PDF Invoices** plugin should have settings related to watermarks. Here's how you can check:

– Go to your **WordPress Admin Dashboard**.
– Navigate to **WooCommerce > PDF Invoices > Settings**.
– Look for a section like **Watermark** or **PDF Customization**.
– If available, adjust the **Watermark Layer** or similar setting to **Background** or **Behind Content**.
– Save the changes and regenerate the PDF invoice to check the results.

#### 2. Adjust Watermark Position Using Custom CSS (Dompdf)
Since you are using **Dompdf** in your environment, adding custom styles might help adjust the watermark's position.

– Go to **WooCommerce > PDF Invoices > Custom Styles**.
– Add the following CSS to ensure the watermark is positioned behind the content:

.watermark {
    position: absolute;
    z-index: -1; /* Ensure watermark is behind other elements */
    opacity: 0.1; /* Adjust opacity as needed */
}

– Save changes and regenerate the PDF to see if it fixes the issue.

#### 3. Edit the PDF Template (If Custom Templates Are Used)
If you're using custom templates for your PDF invoices, you may need to adjust the template file to ensure the watermark is rendered before other content.

– Go to your custom template directory:
– Typically located in `wp-content/uploads/woocommerce-pdf-invoices/templates/`.
– Open the template file (like `invoice.php` or a similar file).
– Look for the watermark rendering code and move it before other content sections if it's not already there.

For example:

// Add watermark before other content
$pdf->Image($watermarkImagePath, $x, $y, $width, $height, '', '', '', true, 300, '', false, false, 0, false, false, true);

#### 4. Clear Cache and Regenerate PDF
After making adjustments, clear any caching mechanisms that might affect the PDF output and regenerate the invoice:

– Clear WooCommerce or site cache (if applicable).
– Go to **WooCommerce > Orders**.
– Select an order and click on **Download PDF Invoice** to check the watermark placement.

#### 5. Rollback to Previous Version (If Necessary)
If none of the above solutions work, you might want to temporarily roll back to the previous plugin version that worked correctly:

– Download the previous stable version from the [plugin's repository](https://wordpress.org/plugins/woocommerce-pdf-invoices/advanced/).
– Deactivate the current version and install the previous one.
– Test the PDF generation again to confirm that the watermark behaves as expected.

#### 6. Contact Plugin Support
If you're still facing issues, there might be a bug in the recent update (version 5.0.5). You can reach out to the official support:

– Visit the [plugin's support forum](https://wordpress.org/support/plugin/woocommerce-pdf-invoices/) to report the issue.
– Include details about your setup (WordPress version, WooCommerce version, plugin version, and any customization you have).

These troubleshooting steps should help you adjust the watermark so it no longer overlaps the text in your WooCommerce PDF invoices.
