When I click on “Add New Client” all I get is empty frame. I inspected frame, but it contains only empty body `` I tried to open frame link in separate tab, but I got same result. * any help would be appreciated 🙂 * [https://wordpress.org/plugins/oauth2-provider/](https://wordpress.org/plugins/oauth2-provider/) Viewing 5 replies - 1 through 5 (of 5 total) * Plugin Author [Justin Greer](https://wordpress.org/support/users/justingreerbbi/) * (@justingreerbbi) * [10 years, 1 month ago](https://wordpress.org/support/topic/cannot-create-client/#post-7264914) * The frame calls a protected endpoint of the plugin. Are there any sever errors in your server logs? * You can try any of the following as well. * – Deactivate and reactivate the plugin (maybe rewrites did not update properly the first time) – Setting WP permalinks to default and or pretty permalinks and trying again. – Deactivate all other plugins and try again (security plugins may cause this). If there is a security plugin causing the issue, please let me know which one and what version so I can investigate the issue. * Thanks * Thread Starter [nktobias](https://wordpress.org/support/users/nktobias/) * (@nktobias) * [10 years, 1 month ago](https://wordpress.org/support/topic/cannot-create-client/#post-7264939) * Hi, thank you for fast response 🙂 I run fresh WP instalation, no other plugins are installed, permalinks are set to ‘Post name’ or ‘Plain’ I tried deactivating and activating plugin none of above helped after activating plugin, i got this message * `The plugin generated 6336 characters of unexpected output during activation. If you notice “headers already sent” messages, problems with syndication feeds or other issues, try deactivating or removing this plugin.` * I checked apache logs, but nothing special was there if there is anything else I can try please help 🙂 thank you very much * Thread Starter [nktobias](https://wordpress.org/support/users/nktobias/) * (@nktobias) * [10 years, 1 month ago](https://wordpress.org/support/topic/cannot-create-client/#post-7264965) * Hi, I have a little update I used plugin to get that extra 6336 characters and I get these two warnings * `Warning: openssl_pkey_export(): cannot get key from parameter 1 in C:\wamp\www\ wp\web\wp-content\plugins\oauth2-provider\wp-oauth-main.php on line 275` * `Warning: openssl_pkey_get_details() expects parameter 1 to be resource, boolean given in C:\wamp\www\wp\web\wp-content\plugins\oauth2-provider\wp-oauth-main. php on line 278` * then on my php server I turned off php extension php_openssl, but unfortunately no luck * Plugin Author [Justin Greer](https://wordpress.org/support/users/justingreerbbi/) * (@justingreerbbi) * [10 years, 1 month ago](https://wordpress.org/support/topic/cannot-create-client/#post-7264976) * umm. There may be a file permission issue where WordPress can not create the needed keys. * Download and extract the Keys directory into the “library” directory of the plugin. [https://wp-oauth.com/wp-content/uploads/2016/04/keys.zip](https://wp-oauth.com/wp-content/uploads/2016/04/keys.zip) * Try it and let me know * Plugin Author [Justin Greer](https://wordpress.org/support/users/justingreerbbi/) * (@justingreerbbi) * [10 years, 1 month ago](https://wordpress.org/support/topic/cannot-create-client/#post-7265042) * Did you ever get around to figuring out what the issue was or is?
