We appear to be experiencing our 1st ever system-wide issue merging images & signatures. It appears to be an update to the image engine. We are aware of the issue and will work nonstop to fix it. We’ll reply again once the issue is resolved.
Sounds like you are using the free version of the plugin, or you have not selected the “Signature” option from the “Format” dropdown for each of the signature field mappings.
If you are using the free version you’ll need to purchase the paid version, if you are using the paid version and have “Signature” selected from the “Format” dropdown, then we may need to take a look at one of your installations to determine the issue. Complete this form if possible, otherwise reply to this email for additional troubleshooting.
