@royalwebraisers

Hi, I understand you need to debug a legacy OpenCart 2.0.3.1 store where the iSenseLabs Square extension connects successfully but fails to render card fields at checkout, likely due to JavaScript, AJAX, or API callback conflicts within the existing theme or checkout flow. Implementation Approach: • Inspect console logs, JS conflicts, and AJAX responses • Trace extension controller/model/payment scripts • Validate Square API token, callbacks, and SDK loading • Patch frontend or server-side integration issues Queries: • Custom theme or default checkout? • Any recent extensions installed? • Server PHP version? I will share my portfolio on your first message and am confident about delivery after this first meeting. Kindest Regards,

@purplemaestro

Hi. I have extensive experience fixing payment gateway integrations in OpenCart, particularly with Square's card field loading issues. I'll start by debugging the JavaScript console and AJAX requests to identify the root cause, then check for conflicts with your theme, jQuery version, or vQmod/OCMod modifications. I can provide a quick diagnostic within 24 hours and implement a permanent fix that ensures smooth Square payment processing. My approach includes thorough testing across different browsers and devices to prevent future issues. I'm available to start immediately and can deliver the solution within your timeline and budget.

@Feriver

Hello, I understand you’re looking for an experienced OpenCart developer to diagnose and fix a broken Square payment integration on a legacy OpenCart 2.0.3.1 installation where vendor support is no longer available. I have hands-on experience debugging discontinued OpenCart extensions, particularly payment gateways that fail due to frontend JavaScript, AJAX, or outdated API handling. My approach is systematic and low-risk. I will trace the checkout flow end to end, inspect browser console and network activity, and identify where the Square card fields fail to initialize. This typically involves resolving JavaScript conflicts, fixing deprecated Square API callbacks, correcting tokenization scripts, or adjusting AJAX responses blocked by SSL, CSP, or mixed-content issues common on older OpenCart builds. All fixes will be applied directly to the existing extension code without altering unrelated checkout logic. The goal is a fully functional checkout where card fields render correctly and payments process reliably, along with clear hand-off notes explaining the root cause and any recommended stability or compatibility improvements. Thanks, Asif

@ayesha0124

With my extensive background in OpenCart development and payment integration, I'm confident in my ability to diagnose and resolve the AJAX issue you’re encountering with the card input fields. I'll thoroughly examine the existing code for any JavaScript conflicts or API callback issues that may be causing the loading failure. My approach will ensure not just a fix, but a seamless checkout experience for your customers. I aim to provide a diagnosis and resolution within three days, including any recommendations for module updates or Square settings to enhance functionality.
