We recently installed the Image Watermark plugin in WordPress 4.8.3 and noticed a few issues:
1. Clicking the “Apply Watermark” link on a single image causes a spinner that never finishes the action. The watermark is only (sometimes) applied after refreshing the browser window.
2. The Bulk Apply Watermark does the same as #1, but never moves past the first image, so it is not functional.
Any thoughts on what needs to happen to fix these issues?
