"...We spent three weeks trying to fix a problem with the checkout process.

An online store. Payments were failing on the first attempt. Credit card fields weren't displaying correctly on mobile devices. The client was losing sales daily, and no one knew why.

So, we did what everyone does: we swapped out the payment plugin. Then we swapped it again. We ran a full security scan with Wordfence Premium—nothing detected. We tweaked the reCAPTCHA. We cleared the cache, tested across different browsers, disabled features one by one, and combed through the payment gateway logs line by line.

Each fix worked for a moment. Then, the problem would return.

Three weeks. Neither the client nor we had the slightest clue what was going on.

Only then did we hear about Site Doctor and decide to give it a try.

It turned out to be a credit card-stealing script. It was injected into the checkout process, hidden inside a legitimate snippet of code the team had written weeks earlier. The payload was Base64-encoded and stored in a variable named to mimic a reCAPTCHA license key—with a typo so subtle that it looked like "recaptcha" and was simply overlooked. It only executed on the checkout page, so all the tests we ran elsewhere came back clean.

It had been stealing data from that store the whole time we were blaming the payment gateway, the cache, and the browser.

From the moment we ran the scan to the moment the site was fixed: about an hour.

Three weeks of guesswork. One hour once we could see what was happening under the hood. ... So thanks SYSWP and thanks Site Doctor... we use it on all our projects now...."
