##  Server configurations

To access these fields please edit “php.ini” file which is located in host (if you can’t find it then contact with your host service provider) 

upload\_max\_filesize = 32M

post\_max\_size = 48M

memory\_limit = 128M

max\_execution\_time = 600

max\_input\_vars = 10000

max\_input\_time = 400

## WordPress Configurations

To change the PHP memory limit in your website’s wp-config file, open it carefully and make sure you only edit the line that reads “define(‘WP\_MEMORY\_LIMIT’, ‘512M’).” Keep in mind that the wp-config file is sensitive and editing anything else could cause your website to break.

define('WP\_MEMORY\_LIMIT', '512M');
