Hi @ongraphdev,

You can find information on increasing the memory limit here.

Cheers,

536870912 bytes is 512 megabyte which is ridiculously high already.

Instead of increasing the limit it is worth while solving the cause.

TS shouldp provide more info. Install query monitor and check if there is a high query count and if so which plugin or function is causing this.

Hi,

If you found the bug, please provide as much detail as possible. Have you tried disabling all third-party plugins and customizations? Does the issue only occur with dropdowns that have many options to select from? Does it happen on a fresh installation as well?

Including these details will help us identify and resolve the issue more quickly.
