Title: LearnDash error Last modified: October 19, 2022 --- # LearnDash error * Resolved [qwik3r](https://wordpress.org/support/users/qwik3r/) * (@qwik3r) * [3 years, 7 months ago](https://wordpress.org/support/topic/learndash-error/) * I just installed this plugin and it instantly created a critical error on my site. According to the automatic error email that is sent out, it appears that LearnDash relies on part of the REST API and I guess by it being turned off by default messed something up. I had to rename my LearnDash folder to get back into the site. * ``` An error of type E_ERROR was caused in line 553 of the file /home/xxxx/public_html/wp-content/plugins/sfwd-lms/includes/rest-api/v2/class-ld-rest-essays-controller.php.

I may have an idea on how to fix, and sent you a message on Slack to follow up. Hope to talk to you soon and see if we can get this fixed for you! * Thread Starter [qwik3r](https://wordpress.org/support/users/qwik3r/) * (@qwik3r) * [3 years, 7 months ago](https://wordpress.org/support/topic/learndash-error/#post-16119854) * Thanks. I’ll check the message there. * Plugin Author [Dave McHale](https://wordpress.org/support/users/dmchale/) * (@dmchale) * [3 years, 7 months ago](https://wordpress.org/support/topic/learndash-error/#post-16126929) * hi [@qwik3r](https://wordpress.org/support/users/qwik3r/) * I believe I’ve tracked down the issue! 🤞 Unfortunately I’m troubleshooting a UX update for the next version of this plugin that is holding up my next release, but this change WILL be included in the next version. * If you would like to make an update now for yourself you can edit Line 32 of `\ disable-json-api\classes\disable-rest-api.php` and change the `init` action to` wp_loaded` – in my local environment that seems to work without any negative side effects that I have noticed. But please let me know if you see any issues, if you decide to try this update! * Thanks again for the report, and hope this helps you use the plugin without issue! * Thread Starter [qwik3r](https://wordpress.org/support/users/qwik3r/) * (@qwik3r) * [3 years, 7 months ago](https://wordpress.org/support/topic/learndash-error/#post-16129258) * That seemed to do the trick in resolving the critical error. I’ll keep an eye out for any other issues. Thanks! * I’m having some trouble connecting to Metorik even though that has been checked off as being enabled under the settings. ;\ - This reply was modified 3 years, 7 months ago by [qwik3r](https://wordpress.org/support/users/qwik3r/).

And sometimes even if you’re logged in as a particular user/role, endpoints are sometimes accessed without authentication. I’d recommend looking at that as a starting point. * Since we’ve confirmed the plugin no longer causes fatal errors on your site I’m going to close this ticket now, but feel free to let me know if you have any continued issues in a new ticket!

All I know is that the plugin is blocking it. When disabled it doesn’t block it. In their docs they state to make sure that app.metorik.com is not blocked. There are endpoints that show up in the settings for metorik, such as authentication, but turning those off does nothing. Please advise. * [bryceadams](https://wordpress.org/support/users/bryceadams/) * (@bryceadams) * [3 years, 7 months ago](https://wordpress.org/support/topic/learndash-error/#post-16130752) * Hey [@qwik3r](https://wordpress.org/support/users/qwik3r/) – Bryce from Metorik here. We use quite a few of the WooCommerce API endpoints, and also add some of our own through the Metorik Helper plugin, so you’ll just want to make sure those API endpoints aren’t disabled. Any specific issues, perhaps shoot us a message through our support so we can test for your site specifically and can let you know any errors.

I can confirm that for ‘unauthenticated users’ in this plugin’s settings anything relating to Woocommerce and anything that says Metorik are not blocked. I’ve been in touch with [@dmchale](https://wordpress.org/support/users/dmchale/) privately to try to resolve this as well. * Thanks. * Plugin Author [Dave McHale](https://wordpress.org/support/users/dmchale/) * (@dmchale) * [3 years, 7 months ago](https://wordpress.org/support/topic/learndash-error/#post-16135736) * [@qwik3r](https://wordpress.org/support/users/qwik3r/) I think at this point taking [@bryceadams](https://wordpress.org/support/users/bryceadams/) up on his offer to look would be ideal, since nothing about DRA should be blocking anything if you’ve tried adjusting your settings to “allow full”. Since you’re unable to debug what I sent above, with luck Bryce and team can either find out what else is not working properly or at least help provide more information that I could run with on my end. * Good luck, and keep me in the loop if you find more information! * Thread Starter [qwik3r](https://wordpress.org/support/users/qwik3r/) * (@qwik3r) * [3 years, 7 months ago](https://wordpress.org/support/topic/learndash-error/#post-16136089) * Thanks.
