Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate

Can’ edit anything anymore.

Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 163840 bytes) in /var/www/web1162/html/wp-includes/functions.php on line 3092

What does that mean?
And how can I fix it?

Best, Lale

You can increase your memory limit. See here.

You can also disable the plugin that is causing this.

I can not deactivate any plugins since I have only activated those plugins that are essential for the theme.

I will contact the host.

Thanks for your help.
