Title: REST API error Last modified: March 8, 2022 --- # REST API error * Resolved [Devomo](https://wordpress.org/support/users/devfirst/) * (@devfirst) * [4 years, 1 month ago](https://wordpress.org/support/topic/rest-api-error-30/) * In [thread #15439077](https://wordpress.org/support/topic/could-not-connect-to-the-wordpress-rest-api/page/2/#post-15439077) I was advised to create a new thread specific to my issue, so here it is. I get the following error whenever I try to save some setting from the SG Optimizer settings screen: * > COULD NOT CONNECT TO THE WORDPRESS REST API > Either a security plugin, custom > function, or rules in your .htaccess file is preventing the WordPress REST > API from working properly.

I can hide the pop-up by clicking outside of it, but when I then try to change a setting, the error reappears. * > Could you please check the Site Health and see if there are any particular > errors reported there? * It reports only one problem: imagick is not installed. I can’t imagine this is the cause of the problem. * > In addition, would it be possible to check if there are any specific errors > in the php_errorlog?

I also tried to turn on WP_DEBUG_LOG, but that did not yield any results either; no errors were reported. * However, my JS console said the following: * > Failed to load resource: the server responded with a status of 405 () * Does that provide any insight? * I can also share the Site Health info if that’s okay to do on the forum? * Plugin Support [ivandzh](https://wordpress.org/support/users/ivandzh/) * (@ivandzh) * [4 years, 1 month ago](https://wordpress.org/support/topic/rest-api-error-30/#post-15440358) * Hello [@devfirst](https://wordpress.org/support/users/devfirst/). * The returned 405 error indicates that the specified request was recognized by the server, but the server itself has rejected the method used for the accessed resource. * In order to verify if this is what’s causing the problem, is it possible to provide us with the name of the affected script? * Including any errors reported by the Site Health tool would also be useful, as long as they do not contain sensitive information. * Best regards, Ivan Dzhangozov * Thread Starter [Devomo](https://wordpress.org/support/users/devfirst/) * (@devfirst) * [4 years, 1 month ago](https://wordpress.org/support/topic/rest-api-error-30/#post-15440850) * Hi [@ivandzh](https://wordpress.org/support/users/ivandzh/), * Thanks for replying! I have managed to narrow down the issue a bit. The problem is: my server does not allow PUT requests. * In WordPress core, this never is a problem, because WordPress always only uses GET/POST request methods. However, the REST API allows other methods te be registered too, which is what the plugin does. But the REST API also allows you to _override_ the request method using the query string or a header, see [https://developer.wordpress.org/rest-api/extending-the-rest-api/routes-and-endpoints/#http-methods](https://developer.wordpress.org/rest-api/extending-the-rest-api/routes-and-endpoints/#http-methods). The WordPress developers seem to have taken into account servers like mine, which do not allow other methods than GET/POST/HEAD. * This would in practice mean that you guys can replace the PUT request by a POST request and then override the method using one of the tricks described on the page linked above. This should only require a change in the plugin’s JS, not in the REST route registration. * Of course, I can try to change the configuration of my server to allow PUT requests. But since there were more people on the forum who reported the same problem, and since WordPress itself provides a mechanism to work around this, would it be possible for you guys to implement this in the plugin? * Cheers! * Plugin Support [Dimitar Petrov](https://wordpress.org/support/users/demiro/) * (@demiro) * [4 years, 1 month ago](https://wordpress.org/support/topic/rest-api-error-30/#post-15441123) * Thank you for your collaboration. * I have reported the case to our developers and they will consider the requested feature. * Best Regards, Dimitar Petrov * Thread Starter [Devomo](https://wordpress.org/support/users/devfirst/) * (@devfirst) * [4 years, 1 month ago](https://wordpress.org/support/topic/rest-api-error-30/#post-15441596) * Thanks [@demiro](https://wordpress.org/support/users/demiro/)!

Indeed, the WordPress application allows overriding HTTP methods used by the client, however, this is a workaround for specific environments and not the standard. We follow strictly the standards and best practices. * If you maintain such an environment, I would recommend allowing all default HTTP verbs required by the WordPress app. * Regards, Dimitar * Thread Starter [Devomo](https://wordpress.org/support/users/devfirst/) * (@devfirst) * [4 years, 1 month ago](https://wordpress.org/support/topic/rest-api-error-30/#post-15448520) * Hi there, * Thanks for the reply and the time invested in this.
