Title: REST API & loopback request errors Last modified: August 23, 2019 --- # REST API & loopback request errors * [Ricardo](https://wordpress.org/support/users/maverickws/) * (@maverickws) * [6 years, 9 months ago](https://wordpress.org/support/topic/rest-api-loopback-request-errors/) * I have performed several tests to isolate the culprit of the event, which is, when the WHMCS-Bridge plugin is enabled, the “Site Health” tool on WP throws the following errors: * > **The REST API encountered an error** > The REST API is one way WordPress, and > other applications, communicate with the server. One example is the block editor > screen, which relies on this to display, and save, your posts and pages. > The REST API request failed due to an error. > Error: [] cURL error 28: Operation > timed out after 10000 milliseconds with 0 bytes received * and * > **Your site could not complete a loopback request** > Loopback requests are > used to run scheduled events, and are also used by the built-in editors for > themes and plugins to verify code stability. > The loopback request to your site failed, this means features relying on them > are not currently working as expected. > Error: [] cURL error 28: Operation > timed out after 10001 milliseconds with 0 bytes received * it also triggers a recommended improvement warning: * > **Background updates may not be working properly** > Background updates ensure > that WordPress can auto-update if a security update is released for the version > you are currently using. > – Warning Could not confirm that the `wp_version_check()` filter is available. > > + Passed No version control systems were detected. + Passed Your installation > of WordPress doesn’t require FTP credentials to perform updates. + Passed All > of your WordPress files are writable. * I have disabled all the plugins and performed some tests: – All plugins disabled, but whmcs-bridge alone triggers these errors. – All plugins enabled but whmcs- bridge, no error on Site Health. * I opened a support ticket over 24 hours ago had no reply so hopping I’ll get some help here. - This topic was modified 6 years, 9 months ago by [Ricardo](https://wordpress.org/support/users/maverickws/). - This topic was modified 6 years, 9 months ago by [Ricardo](https://wordpress.org/support/users/maverickws/).

Please note that we are just the folks who enforce the rules around all of WordPress.org. * Reporting to moderators doesn’t get any faster support, instead it just kind of attracts attention from folks whose radar you probably don’t want to be on. 😉 * If you really do need a moderator, please add a reply letting us know why before you hit the report button. * Otherwise, please hang in there for the plugin’s support to reply when they can. * Thread Starter [Ricardo](https://wordpress.org/support/users/maverickws/) * (@maverickws) * [6 years, 9 months ago](https://wordpress.org/support/topic/rest-api-loopback-request-errors/#post-11870354) * Hi James, actually that was an accident I didn’t mean to hit the report button. * But mind me asking what do you suggest as the proper approach to a paid plugin whose support simply does not answer. Does not answer here, does not answer via official support tickets… * Moderator [James Huff](https://wordpress.org/support/users/macmanx/) * (@macmanx) * [6 years, 9 months ago](https://wordpress.org/support/topic/rest-api-loopback-request-errors/#post-11871799) * They can only support the free plugin here, and are under no obligation to do so either. * Make sure you try to reach them at [https://i-plugins.com/whmcs-bridge/contact/](https://i-plugins.com/whmcs-bridge/contact/) which appears to be where they want to be reached. * If they don’t help you there either, I suppose you could try asking them for a refund, but that’s up to you. * [surfsideweb](https://wordpress.org/support/users/surfsideweb/) * (@surfsideweb) * [6 years, 8 months ago](https://wordpress.org/support/topic/rest-api-loopback-request-errors/#post-11971894) * They don’t support the Paid plugin either, even from their ticketing system. Takes a month for a reply, god forbid you should respond to that reply, cause then you can add a second month. It’s horrible. Unfortunately there are no other bridge softwares for whmcs and wp.
