The Gravity Forms Campaign Monitor Add-On has been updated to better support other plugins that may also be using the Campaign Monitor PHP API wrapper.
Here is a look at what is new in Gravity Forms Campaign Monitor Add-On v1.9:
- Fixed issue with broken function_exist conditional in API.
- Wrapped all API classes in class_exists() conditional for compatibility with other plugins using the same API.
Please Note: Automatic Upgrade will only work if you have entered a valid Business or Developer License Key in the Settings page of Gravity Forms in your WordPress Administration Panel.
