Ok Guys, I found what is the issue! the problem is wordpress memory and PHP memory. I increased it to 512M and solved the issue. You can start trying with 128M then 256M if not 512M.
for folks that don’t know how to increase it. you should access your files via ftp/file manager then go to wp-includes and edit default-constants.php
if ( ! defined( 'WP_MEMORY_LIMIT' ) ) {
if ( false === wp_is_ini_value_changeable( 'memory_limit' ) ) {
define( 'WP_MEMORY_LIMIT', $current_limit );
} elseif ( is_multisite() ) {
define( 'WP_MEMORY_LIMIT', '512M' );
} else {
define( 'WP_MEMORY_LIMIT', '512M' );
}
}
if ( ! defined( 'WP_MAX_MEMORY_LIMIT' ) ) {
if ( false === wp_is_ini_value_changeable( 'memory_limit' ) ) {
define( 'WP_MAX_MEMORY_LIMIT', $current_limit );
} elseif ( -1 === $current_limit_int || $current_limit_int > 268435456 /* = 256M */ ) {
define( 'WP_MAX_MEMORY_LIMIT', $current_limit );
} else {
define( 'WP_MAX_MEMORY_LIMIT', '512M' );
}
}
