Title: 500 error Last modified: June 14, 2022 --- # 500 error * Resolved [mary2mary](https://wordpress.org/support/users/mary2mary/) * (@mary2mary) * [4 years, 1 month ago](https://wordpress.org/support/topic/500-error-192/) * Last week we wanted to send out our monthly newsletter but got this notification; * De e-mail kon niet worden verzonden vanwege een technisch probleem met MailPoet: Een fout deed zich voor bij het uitvoeren van een verzoek, de server heeft gereageerd met antwoordcode 500 * might this be because Mailpoet isnt tested with the latest WordPress version? Or is it something else? * Hope te hear soon! * TIA Marielle Viewing 4 replies - 1 through 4 (of 4 total) * Plugin Support [Dani F. a11n](https://wordpress.org/support/users/danielinhou/) * (@danielinhou) * [4 years, 1 month ago](https://wordpress.org/support/topic/500-error-192/#post-15737820) * Hi there [@mary2mary](https://wordpress.org/support/users/mary2mary/) πŸ‘‹πŸ½! * Thank you for reaching out to MailPoet Support! * > Last week we wanted to send out our monthly newsletter but got this notification; * Could you please share some additional information?
