I am not sure whether this error is related to a problem you solved yesterday (the colour filters producing an error message), but now the images are not loading on the category pages.
This is happening now on both my staging sites (which previously worked fine), so I am presuming it could have been something that was changed in ftp rather than on individual sites as one of the staging sites has not been touched in the past week or more.
The only category that seems to load the images is
https://staging11.swankypins.co.uk/product-category/stockings/
but most of the others do not – e.g.
https://staging11.swankypins.co.uk/product-category/suspenderbelts/
I have cleared the cache in my browser as I thought maybe this was why i could see the images for one category but not others, but it does not seem to make a difference.
I have attached login details, thank you. Debbie
