No we didn’t try deleting and reuploading. The client didn’t upload the images by spreadsheet so she would need to reupload all the products. There were no changes made in the options or source code but wordpress may have updated itself automatically. no they are not duplicating in the database. it is only happening in one catalogue which is the one that has the most products. Can I send you the link to have a look. Where can I email you the details?
Thanks
