1. Your theme (which is outdated) throws errors:
( ! ) Deprecated: Function create_function() is deprecated in .../themes/dynamik-gen/lib/functions/navbars.php on line 363
This forced me to remove it and use Theme Twenty Seventeen
2. I updated all Toolset Plugins to the latest versions.
3. I updated the expiration and CRON of the duplicate so to test quickly locally.
4. I notice you have a plugin installed:
Disable Emails
Deactivate
Stop WordPress from sending any emails. ANY!
I am not sure it should be there since you want to send emails...
5. However, I left all as is, inclusive Plugins which I fear will block Toolset Forms and submitted the form
I got these emails:
- 1st GoldPlat with Banking Your listing for test is expiring SOON. Please renew (I got this email to the email I set in the problematic notification, but sent was the DISABLED Email to Supplier - Expiry date - 1st RENEWAL)
- That form is set to 30 minutes before the automatic expiration date.... so it CANNOT be sent if I set it to 15 minutes or on the other hand, is triggered IMMEDIATELY as it's "too late".¨
- However, it's a disabled notification and should NOT get fired.
- I got then the final expected email of the expiration at the point where I expected to the email I expected.
So the problem here seems that DISABLED notifications do not disable, they still send.
I can confirm that the second email you receive is not the same, it's another, but it should not be sent, as disabled.
It seems to happen only with that one notification:
I deleted and re-created that notification, which seems to have solved the issue.
To fix this issue I would suggest saving the notification which makes problems to a safe location and then re-add it (new).
That immediately resolved the problem, locally, as well, when I disable the very notification now, this is again respected
I think the form may have been corrupted somehow.
