Magento2.3 - Fatal error: allowed memory size of 536870912 bytes

Question

Migrate from one server to another server.

I have a big problem with this because I cannot understand the logic on it. Magento 2.3.2 and php 7.2

Fatal error: Allowed memory size of 536870912 bytes exhausted (tried to allocate 262144 bytes) in /public_html/vendor/magento/module-store/Model/Config/Placeholder.php on line 146

Answer 1

Please make sure both fields secure and unsecure base_url are filled with proper value.

May be you are directly adding the incorrect value to core_config_data. Magento cannot parse it, and it causes an infinite recursion. If you want to remove some value from core_config_data, you should delete the whole record, not only it's "value" raw.
