# Cannot Connect to WordPress Rest API

 * I’m having a problem with a site I’m developing. I keep getting a message from
   Siteground Optimizer plugin that says: “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. SG Optimizer is using
   it to store its options and other functionalities so please make sure it works
   properly.” I tried contacting their tech support and they said to contact WP 
   support. This error started happening today. I tried resaving my permalinks because
   I read that was helpful but I got a message that my .htaccess file isn’t writeable,
   which is strange because it has 644 permission, which is optimal. My hosting 
   company was not having the same issue when they accessed the website. I cleared
   all my caches including my DNS cache, browser cache, SG Optimizer caches, Cloudflare
   cache. I’m still getting the error message. Any ideas why?

   to see the link]_

 * I did clear my DNS cache and my browser cache again and then logged in again 
   and my access to the site was restored. So something is randomly giving me Rest
   API access issues, apparently.

 * Probably was a cache issue.
 * Glad it’s sorted 🙂
