Title: Function register_rest_route problem Last modified: August 19, 2023 --- # Function register_rest_route problem * Resolved [christodeus](https://wordpress.org/support/users/christodeus/) * (@christodeus) * [2 years, 9 months ago](https://wordpress.org/support/topic/function-register_rest_route-problem/) * Hi, * It’s seems that AI Engine is causing this error: * The register_rest_route function was called incorrectly. The namespace must not start or end with a slash. (This message was added in version 5.4.2.) * Any idea how to fix this?
