https://harrogatepainmanagement.co.uk was built a few years ago, and around 18 months ago the client brought in a marketing company who added some content and some plugins. The site has been kept up to date, and we were brought back in to make some changes. Despite updating everything, deleting the plugins they added, and manually replacing the whole XStore theme folder the header builder refuses to load which is an error I have never seen before. The customer had a fall out with the marketing company, and never thought to ask us to change login to lock them out after they overcharged for very little work and I suspect foul play of some sort
