Hi,
how can i resolve my this type of error logs

Fatal error: Out of memory (allocated 2097152) (tried to allocate 262144 bytes) in /home/hosting.pl/user/domain.pl/public_html/wp-settings.php on line 165

My website: http://www.stolicazdrowia.pl

Changing the memory limit does not solve the problem (.htaccess, php.ini, wp-config.php)

Manual update also has no effect.
Disabling plugins, template also does not change the situation.

Please help me.
