Cannot save more than a limited number of images to Scrollsequence
When adding images to scrollsequence and hitting save, only a limited number of images are getting saved, why?
Navigate to WP-Admin -> Settings -> Site Health -> Server and make sure that max_input_vars is at least 2x greater than number of images you totally use in a sequence.
Each image is a separate variable that gets saved to the database. WordPress has a max_input_vars variable is limiting the amount of images you can upload.
Try increasing that to 5000 and it should all work.
