Template Editor Not working on latest WordPress

Same deal here. Can’t access any of the config tabs all blank after updating yesterday on 2 sites to 3.50.1. Also tested on a virgin site (WP 5.5.1) and same thing. Also tried rolling it back to 3.49.1 but no change.

Hi MR Toast, i just did another test on AWS, and Siteground. With the latest version of WP 5.5.1 and 3.50.1 i can not create a newsletter, after selecting a template it loads a blank screen.

tried rolling back to 3.49.1 as well, same issue. Mailpoet seems to be not compatible with WP 5.5.1, even the email sending via SMTP and the latest woocommerce is not working.

Hi @david2019,

We’re not aware of any conflict between WordPress 5.5.1 and the latest version of MailPoet 3.

Could you please check if you can see any error on the console when trying to access the editor?

I have looked in console and Get Mixed content Errors, But only regarding some mailpoet files…

mailpoet-plugin.efecb526.css
vendor.35298d24.js
mailpoet.35298d24.chunk.js
admin_vendor_chunk.35298d24.chunk.js
admin_vendor.35298d24.chunk.js
admin.35298d24.chunk.js

the entire site is SSL with no other content warnings or errors. I have searched the databases and there are no Http references. This leads me to believe there are issues with Mailpoet.

Hello

Found a solution which has fixed this issue for AWS lightsail users.

add the following code to /opt/bitnami/apache2/conf/httpd.conf

<Location “/”>
SubstituteMaxLineLength 10m
</Location>

then restart apache

sudo /opt/bitnami/ctlscript.sh restart apache

reference: After adding Template to WP page with Elementor plugin I try to edit second time and I get Internal Server Error

thanks

david
