I'm using the email stack to generate an email from a Foundation form. I've been using it for some time without any problems. My users are getting several copies of an error prior to seeing the generated email. The error message is
<br />
<b>Deprecated</b>: strtolower(): Passing null to parameter #1 ($string) of type string is deprecated in <b>/Users/charleshenderson/Library/Containers/com.realmacsoftware.rapidweaver8/Data/tmp/RapidWeaverClassic/671/document-0x413ae5230/RWDocumentPagePreview/rw_common/plugins/stacks/inliner/vendor/symfony/css-selector/XPath/Extension/NodeExtension.php</b> on line <b>161</b><br
Several copies of this is showing up in the email. I have gone back to the email setup in Rapidweaver and no matter what I do I get this error message when I preview the project.
Any ideas?
