when I open edit with tagdiv composer then it was not opened.

Hello,

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/
Sometimes, the issue can be from a plugin conflict, that’s why, please deactivate ALL plugins except tagDiv ones, also if you are using child theme or cache plugin, deactivate them, clear all cache and try again.

Thank you!
