Hi,
Thank you for explaining the issue.
I have tried to replicate the issue on our staging site, but I am unable to reproduce it.
On my staging site, WordPress version 4.9.1 and WooCommerce version 3.2.5 are activated. I have activated Abandoned Cart Lite plugin and tried to add/edit the email template and all the changes are saved successfully.
I have added the image and HTML code in the Email Body section and I am able to add the Email Template. Then I have clicked on “Edit” link for the same email template and all the changes are saved.
I have tried with our default email template and new email template, but I am not able to replicate it.
Please see the video: https://www.screencast.com/t/EEesKzAwakIj
It would be great if you can provide us HTML code of Email Body section & the video of the issue which is occurring on your site.
Also, let me know the theme which you are using on your site.
If you do not comfortable to share the video then you can send me on my “[email protected]” email address.
Regards,
Chetna Bhutka
