'Howdy!
|
|
|
|
Since WordPress 5.2 there is 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.
|
|
###CAUSE###
|
|
First, visit your website (###SITEURL###) and check for any visible issues. Next, visit the page where the error was caught (###PAGEURL###) and check for any visible issues.
|
|
|
|
###SUPPORT###
|
|
|
|
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.
|
|
|
|
###LINK###
|
|
|
|
To keep your site safe, this link will expire in ###EXPIRES###. Don\'t worry about that, though: a new link will be emailed to you if the error occurs again after it expires.
|
|
|
|
When seeking help with this issue, you may be asked for some of the following information:
|

###DEBUG###
|
|
|
|
###DETAILS###'
