Compatiability with WordPress 4.0?

Hi janiesc,

Definitely not, we have tested it with WordPress version 4.0 already, everything is fine!

Try to increase your WordPress available memory with this plugin to 128M: https://www.ads-software.com/plugins/change-memory-limit/

If that doesn’t help, pleas get in touch with us at: https://support.mailpoet.com/

That way we can help you better!

Thanks! It ended up being the plugin – I deleted it and reinstalled and all back to normal!

Cool, good to know : )
