How to Fix Missing Theme Content After Installing a WHMCS Theme Print

If your theme content is missing after installation, the most common cause is that the required language override files have not been uploaded to your WHMCS installation.

Solution

Step 1: Locate the Language Override Files

After extracting the downloaded theme ZIP package, navigate to:

/lang/overrides/

This folder contains the language files required for the theme content to display correctly.

Step 2: Connect to Your WHMCS Installation

Using FTP or your hosting control panel's File Manager, navigate to your WHMCS installation directory and open:

/lang/

Step 3: Check Whether the Overrides Folder Exists

If the /lang/overrides/ Folder Already Exists

Do not overwrite the existing folder or files.

1. Open the language file from your WHMCS installation (for example: /lang/overrides/english.php).
2. Open the corresponding language file from the extracted theme package on your computer.
3. Copy all language variables from the downloaded file (everything after the opening <?php tag).
4. Paste those variables into your existing WHMCS language file before the closing ?> tag (if present).
5. Save the file.

If the /lang/overrides/ Folder Does Not Exist

Simply upload the entire overrides folder from the extracted theme package to:

/lang/

so that the final path becomes:

/lang/overrides/

Step 4: Verify the Result

Once the language override files have been uploaded or merged correctly, refresh your WHMCS client area.

The missing theme content should now display properly.
