Plugin help needed

Hi all - I had a custom plugin made for me recently but I can no longer get in touch with the developer and was wondering if there’s anyone out there offering their services for something like this. It’s a variation of the page lock plugin by pedro borges, and in short data is being lost when saving. I’m hoping it’s a simple job, but beyond my capabilities as a front-end dev. Give me a bell if it’s something you think you can help with or you know of someone - thanks!
