Recently, we have upgrade to v1.9.12. Since then, some e-mails received from users come out with only the string "<!</style>" in the message body. Mainly, it seems that happens with e-mails from Hotmail. We tested in two different environments (local vs production). In a local machine works right but not in production. Then, the problem must be related to the different versions installed. Confguration not working:Confguration working:Any help/clue to fix this issue (without upgrade versions)? Thanks!
