I've implemented this awesome plugin to my premium WP theme and some customers experienced the weird issues. It happened when they're going to add a new item for their slider. Note that I used "list item" type for managing the slider items for the theme.
Here are some cases that I've got so far:
Case 1# They already have 4 slider items and would like to add one more but once they uploaded the image of new item and click "Send to OptionTree", there's no image URL appeared in the upload box but that new image URL replaced the one of previous item instead. As a result, they couldn't have more than 4 items in their slider.
Case 2# Starting like case#1 but rather than the URL replacement, the image URL appeared to the upload box as an attachment URL (ending with "attachment_id=XX" some kind like that.) so the image won't show up.
Case 3# Nothing happened when they clicked "Send to OptionTree".
Do you have any idea of these cases? Is there any way to debug and find out what can cause those problems?
Thanks in advance for your help.
