Does that match your setup? Have you tried the other options in the REST API dropdown in the error? * Thread Starter [jeffeisenberg](https://wordpress.org/support/users/jeffeisenberg/) * (@jeffeisenberg) * [7 years, 7 months ago](https://wordpress.org/support/topic/error-re-json-rest-api/#post-10867443) * I’m going to close this. I realized this was caused because I had changed my local hosts file to trick my computer to thinking my url resolves to the new host… for testing purposes. When i changed actual public DNS, the error went away. * Thanks for the quick response! * Thread Starter [jeffeisenberg](https://wordpress.org/support/users/jeffeisenberg/) * (@jeffeisenberg) * [7 years, 7 months ago](https://wordpress.org/support/topic/error-re-json-rest-api/#post-10867646) * Sorry. I think i spoke too soon. -There are no security plugins and additionally, this is the same site copied over from another host so it has the exact same plugins as the site that works. -I also tried all the different drop down options which give the same errors. -The plugin status for all items say good under support. See below. -The only thing i could think that’s different are maybe PHP settings? Could that have an affect? * WordPress REST API Good WordPress REST API is working at [https://www.sfveincenter.com/wp-admin/admin-ajax.php?action=red_proxy&rest_path=](https://www.sfveincenter.com/wp-admin/admin-ajax.php?action=red_proxy&rest_path=) Redirection routes Good Redirection routes are working Database tables Good All tables present Valid groups Good Valid groups detected Valid redirect group Good All redirects have a valid group Post monitor group Good Post monitor group is valid Site and home protocol Good Site and home are consistent * Thread Starter [jeffeisenberg](https://wordpress.org/support/users/jeffeisenberg/) * (@jeffeisenberg) * [7 years, 7 months ago](https://wordpress.org/support/topic/error-re-json-rest-api/#post-10867801) * It’s a memory error. I found it in CPanel caused by Ajax. What’s strange is PHP allows 512 and WP is asking for 256 and tried 512 so it shouldn’t run out. I may just try a VPS instead. * Thanks * [Robey Lawrence](https://wordpress.org/support/users/robey/) * (@robey) * [7 years, 3 months ago](https://wordpress.org/support/topic/error-re-json-rest-api/#post-11265685) * Just wanted to add my scenario here in case it helps anyone else. * I was working on a staging copy of a site that I had duplicated to my server. I was accessing it via https, however I must have chose to add an exception to the browser and I had not installed an SSL on the staging server. This was causing a connection point from being blocked due to mixed content. * After installing an SSL and reconfiguring the Really Simple SSL plugin, the REST API was happily connecting again.
