I am trying to integrate professional templates using pretty mail extension, however every time I do change on the forum that is supposed to trigger sending email, I get an error. Mail is not sent. In the logs I see following message:
[2022-05-29 09:46:58] flarum.ERROR: Exception: ParseError: syntax error, unexpected token "&" in /flarum/app/vendor/fof/pretty-mail/src/BladeCompiler.php(28) : eval()'d code:133
I suppose that syntax of template is not 100% html compatible and some symbols should be screened for parser to work, right? Is there any reference for what should be screened or avoided in templates?
Sorry if this is stupid question, but I am not a PHP guy, so bear with me please.
