Error message

I get this error message

Fatal error: Allowed memory size of 67108864 bytes exhausted (tried to allocate 12288 bytes) in /home/aplatania/public_html/rarepicturesrelease/wp-content/plugins/woocommerce/includes/gateways/cod/class-wc-gateway-cod.php on line 41

I got that after i had several problems with the W3 Total Cache plugin (Object Cache) and tried to resolve it but at the moment i dont know what to do

Would be happy when someone can help me.
