WordPress Developer for Website Updates

Wanted an experience WordPress / coding freelancer developer with at least 5 years’ experience quoting reasonable fees. Must be 100% honest as I’ve used loads of freelancer of developers in the past and most say they can implement the work but really couldn’t, so please don’t waste your or my time. I’ve got a fully loaded market website which has developed an issue – please read URGENT – PRODUCT IMAGE UPLOAD ISSUE The product upload form allows up to 6 images. Images 1–5 upload and are processed successfully through the Poof.bg background-removal API. When I attempt to upload image 6, I receive: “YOUR SESSION AS EXPIRED. PLEASE REFRESH THE PAGE AND TRY AGAIN.” I’ve used Windows 11, Windows 7 and tablet, I have cleared browser history/cache and restarted the computer, but the problem remains. But the issue does not happen with Apple My Poof.bg account has sufficient credits. I’ve been in contact with ChatGPT and I’ve managed to get quite a lot tips which could be useful for you.
