I asked chatgpt, and tested on staging and also on live site and it seems to be working. Please see below for anyone that may be encountering this issue…

🔍 Summary of the Error

Your WordPress site is encountering a critical error caused by the WooCommerce Square plugin. The issue is:

TypeError: Unsupported operand types: string + string
File: /woocommerce-square/includes/Gateway/API/Requests/Orders.php
Line 292

This error means the code is attempting to use the + operator on two string values, which is not valid in PHP. In PHP, string concatenation should use the . (dot) operator, not +. 🧱 Root Cause

The offending file is part of the Square plugin (woocommerce-square) and specifically within this method call stack:

• Orders->get_api_line_items(...)
• Orders->set_order_data(...)
• API->create_order(...)
• Payment_Gateway_Direct->process_payment(...)

So when an order is placed (likely during checkout), the plugin tries to construct line items or order data but incorrectly adds two string variables using +. 🔁 Repetition

This error happens multiple times (09:16, 13:26, 13:28, 13:30), suggesting:

• It’s affecting multiple customers
• It hasn’t been resolved between those attempts
• Likely triggered during every checkout that uses Square

🛠️ Recommended Fix

1. Temporary workaround (if urgent):
   • Disable the Square for WooCommerce plugin to restore checkout functionality.
   • Switch to an alternate payment method temporarily.
2. Permanent fix:
   • Edit /woocommerce-square/includes/Gateway/API/Requests/Orders.php
   • Locate line 292 and replace the + with a . if the intent was string concatenation.
   • Example: phpCopyEdit// Incorrect: $string = $value1 + $value2; // Correct: $string = $value1 . $value2;
3. Better long-term approach:
   • Update the WooCommerce Square plugin to the latest version (if available).
   • If you’re already on the latest version, report the bug to the plugin developers.

🧪 How to Investigate Further

• Open the file at /plugins/woocommerce-square/includes/Gateway/API/Requests/Orders.php
• Navigate to line 292
• Inspect the surrounding code to verify what variables are being combined

If you’d like, I can help write a corrected version of the problematic line if you paste that part of the code here.

Hi Kris,

This seems to be working now. I cleared and re-started the settings. I believe it was because I was manually typing {email-1}, rather than using the ‘+’ button to select it.

You can close this thread. Thanks for your assistance!

Hi Patrick,

Sorry, I was unavailable to respond last week.

Here is the link: https://bar-eivissa.co.uk/premier-league-pass/

The price text is white, and should be black and the button should match the styling of the website. If you could help I would appreciate it.

Kind Regards,

Mike.
