it seems to have fixed itself now!
Also the arrows are not evenly spaced on the images so I have hidden them, the dots end up well below the images so I’ve hidden them but the gap between the carousel and the rest of the content is huge. I can’t find anything about this online.
Thanks for the help, it looks like that person had a similar problem to me but I don’t understand how to disable the Image Cropping feature from General Settings, I’ve tried googling but to no avail! Any ideas where i find this?
There are very few plugins installed (recently updated the whole site and got rid of a lot that were unnecessary) so don’t have those installed.
