You need to increase PHP memory_limit on your server in several ways

PS. Backup any files you edit to be able to restore them in future.

1. Add below line to your WordPress wp-config.php file via FTP:

define('WP_MEMORY_LIMIT', '256M');

2. If you have access to your PHP.ini file, change the below line in PHP.ini to 128M or 256M

memory_limit = 256M;

3. If you don’t have access to PHP.ini Then add below line to .htaccess file:

php_value memory_limit 256M

4. If all the methods mentioned above didn’t help, create a file called php.ini in the wp-admin folder of WordPress install and then add the following line to the file:

memory_limit = 256M;

5. Contact your hosting provider or server support and ask them for fixing problem or increasing PHP memory_limit.
