please find my plugin environment attached.
- Avada Theme version 3.8.6
- WordPress 4.3 (Multisite)
- On this site, there is only SLP and a few other plugins, see plugin list attached.
Before the SLP update I was using:
- WordPress 4.2.4 (Multisite): was updated before updating SLP
- Avada 3.8.4: was updated before updating SLP
- SLP 4.2.67
- Contact Extender 4.2.02
- Pro Pack 4.2.15
- Tagalong 4.2.03
Today I checked the issue and confirm: When I removed one location from the list this did result in the select button in the Store Settings Page being reset to unchecked!
I did backup before resetting, but I prefer not going back to the previous condition because that had another glitch in SLP.
Hope this helps finding the source of this brain teasing issue.
