I get this error, when I try sending a test e-mail from the status page, and some subscribers does not get any newsletter;
Last test failed with error “Undefined index: name”.
I also have these errors;
You have the PHP opcache active with file validation disable so every blog plugins update needs a webserver restart!
The recommended charset for your database is utf8mb4 to avoid possible saving errors when you use emoji. Read the WordPress Codex conversion instructions (skilled technicia required).
What do I do???
