But it is not working. There are two messages appear: * Plugin Status 1. WordPress REST API Problem REST API returns an error code ( 40x – [http://smmc.or.id/wp-admin/admin-ajax.php?action=red_proxy&rest_path=](http://smmc.or.id/wp-admin/admin-ajax.php?action=red_proxy&rest_path=)) 2. Redirection routes Problem REST API is not working so routes not checked * When I try click “magic fix”, a message appears: Fatal error: Call to a member function register_route() on null in /home/adminsmmc/public_html/wp-includes/ rest-api.php on line 77 * Right now, I cancle to change the permalinks for a while, until I have the answer to fix it. * Please help me to fix these problems.

What is the redirect you created that isn’t working? * Regarding the second problem, I’ve never seen that before. I suspect it may disappear if you upgrade WordPress to the latest version. I’ll need to check the plugin against version 4.8.5 * [Tony G](https://wordpress.org/support/users/starbuck/) * (@starbuck) * [8 years, 3 months ago](https://wordpress.org/support/topic/problem-rest-api/#post-9966850) * [@johnny5](https://wordpress.org/support/users/johnny5/), I know you made changes in this area recenty. I came to the forum today because I have the same (first) issue with the status when using the REST API. * > WordPress REST API Problem REST API returns an error code > (40x – [https://xxxxxxxxxxxxx/wp-admin/admin-ajax.php?action=red_proxy&rest_path=](https://xxxxxxxxxxxxx/wp-admin/admin-ajax.php?action=red_proxy&rest_path=)) > Redirection routes Problem REST API is not working so routes not checked * During my search I stumbled on another report of the same problem, with the reporter citing a conflict with another plugin and Redirection. I commented there with a workaround/resolution, and am adding a [ref here](https://wordpress.org/support/topic/your-plugin-rest-api-usage-interferes-with-others/) for your review.

I’ve tried to add a workaround in Redirection, but it’s likely to be quite fragile. * Fortunately as you say it doesn’t touch the REST API, so that’s a solid solution. * [omenaf](https://wordpress.org/support/users/omenaf/) * (@omenaf) * [8 years ago](https://wordpress.org/support/topic/problem-rest-api/#post-10310842) * After install Formidable Forms plugin, I’ve received ‘Fatal error: Call to a member function dispatch() on null in /home/saudecor/public_html/wp-includes/ rest-api.php on line 278’ mensage. * I can not do anything on my website. * [@adminsmmc](https://wordpress.org/support/users/adminsmmc/), how do you solve rest api problem? * [jaydutde](https://wordpress.org/support/users/jaydutde/) * (@jaydutde) * [7 years, 9 months ago](https://wordpress.org/support/topic/problem-rest-api/#post-10634606) * I am facing a similar issue. please let me help out.
