I struggle to send emails with the Newsletter plugin and I don’t know how to solve the issue.
In the General Check page, I have 2 errors:
– MAILING: Last test failed with error “Illegal offset type”.
– DATABASE CHARSET: Charset: iso-8859-1
The recommended charset for your database is utf8 or utf8mb4 but the conversion could be tricky. If you’re not experiencing problem, leave things as is.
Hi the database charset could not be a problem, even if a more modern encoding could help in storing special characters, like the emoji. The error on mailing I something new to me, you should ask the provider.
