Hi there @raminzr,

I would recommend adding a PHP info file to your site to see if the memory limit change is actually taking effect:

<?php

phpinfo();

?>

Also after adding the info PHP file cross-check the location of the php.ini file and make sure that the changes that you are making are in that file.

Note that after changing the values in your php.ini file you might have to restart Apache.

If this still does not work I would suggest checking the contents of the /var/www/html/wp-content/plugins/td-composer/ folder and making sure that it does not contain any suspicious files.

What you could try doing is to temporarily rename the plugins folder to something like plugins-backup and create an empty plugins folder.

Let me know how it goes.
Regards,
Bobby
