Why do my art gallery pop ups stop working?
I have DW CS6, but the problem has started with earlier versions for the past few years.
101 Art Gallery - Fazal Ali 2017
This is a page where I created thumbnails of art works that pop up and enlarge to medium sized pictures.
After uploading, everything works well. But when I make changes to the page, maybe text and reupload, the pop up function stops working. Worse, this homepage has hundreds of pages and old galleries from years ago which are also supposed to pop up at all times. But when I make a change to the template for example, like adding a link ( which changes all pages made from it), then, after reuploading all pages, every page that has a gallery on it with pop ups, stop working? I then have to select one thumbnail on each page, and make it pop up, then save the entire page and then all pop ups on that page work again. This is a lot of work to do each time I make a change.
Why do the pop ups stop working after reuploading an html page>
This started years ago, but did not happen with earlier versions of DW like CS3
Urgent solution needed!
