Critical Error

Hi

Trust you are doing well, i did the updates on MasterStudy LMS WordPress Plugin and now if i check out on my memberships it results in critical WordPress error, see issue below:

WordPress has a built-in feature that detects when a plugin or theme causes a fatal error on your site, and notifies you with this automated email.

In this case, WordPress caught an error with one of your plugins, MasterStudy LMS WordPress Plugin – for Online Courses and Education.

First, visit your website (https://dolife.io/) and check for any visible issues. Next, visit the page where the error was caught (https://dolife.io/wp-admin/admin.php?page=pmpro-member&user_id=30) and check for any visible issues.

Please contact your host for assistance with investigating this issue further.

If your site appears broken and you can’t access your dashboard normally, WordPress now has a special “recovery mode”. This lets you safely login to your dashboard and investigate further.

To keep your site safe, this link will expire in 1 day. Don’t worry about that, though: a new link will be emailed to you if the error occurs again after it expires.
