This morning I updated to Newspaper 10.3.9.1 and immediately I lost all access to the TD Composer tool, getting a “This site can’t be reached” error. I had been using TD Composer earlier and had made no other changes to the website or any plugins. I tried rolling back Newspaper to the 10.3.69 version but it still does not work.
Looking for other avenues to try…

Hello,
Usually, this error appears when the requirements aren’t set like in our guide, please make sure you have added the limit also in your wp-config.php file, in config is WP_MEMORY_LIMIT not PHP Memory Limit (there is a typo, sorry) – https://forum.tagdiv.com/requirements-for-newspaper/
please increase all lower requirements and follow all steps;
Also, please check your cache and delete it even from your browser.
