i Can't activate the plugin.

Hello,

Please try to increase PHP memory limit.

Hope that helps.

Thank you.

I did increase the php memory limit but does not work as.. I receive the fatal error as well. Plugin could not be activated because it triggered a fatal error. Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to allocate 24 bytes) in C:\inetpub\wwwroot\wpsite\wp-includes\wp-db.php on line 2258

I’ve disabled all the plugins, change the theme. change the php.ini file memory_limit = 2048M
even change the .htaccess file php_value memory_limit 2048M

as well as the wp-config.php file: define(‘WP_MEMORY_LIMIT’, ‘2048MB’);

I even change the 2048 higher and lower but nothing works.

it’s working now! I have to manually activate the plugin:

Got to mysql:
change wordpress to your database name
SELECT * FROM wordpress.wp_options WHERE option_name = ‘active_plugins’;
