Message: There has been a critical error on this website

Please enable the debug log and then get the error message then we’ll able to guide how to fix that error.

You can read about debugging here:

Debugging in WordPress

Thank you for your response. Unfortunately, I have little to no knowledge of the technical aspects of web pages. How and where do I enable the “debug log”? Especially since I cannot access the webpage.

You can access error logs from your Cpanel as well if you are not good with technical things. Without the error message it’s hard to know which plugin is causing the issue.

You can ask the hosting support to access the error logs then you can provide us the last 10-20 error logs, then we will be able to guide you to resolve the issue.

You suggested that I ask the hosting support to access the error logs so I can provide you with the last 10-20 error logs, so you will be able to guide me to resolve the issue. I have?accessed the wordpress.com?site and do not find any link to obtain hosting support.

However, I was able to run a debug through Jetpack and this is the return I received:

XML-RPC is not responding correctly ( 500 )
It looks like XML-RPC is not responding correctly. Please make sure XML-RPC is turned on for your site and is set up to respond to all content types. You can test this yourself by running the following command from the command line:

curl -A 'Jetpack by WordPress.com' -d '<methodCall><methodName>demo.sayHello</methodName></methodCall>' https://delamanodemaria.com/xmlrpc.php
The answer should be:

<?xml version="1.0" encoding="UTF-8"?>
<methodResponse>
  <params>
    <param>
      <value>
      <string>Hello!</string>
      </value>
    </param>
  </params>
</methodResponse>
If you continue to get this error, please check out our troubleshooting guide or contact support.

I tried running the suggested command and did not get a response. Also, with my limited technical knowledge I have tried to access the files to deactivate the plugins by installing several external FTP client servers and none can access the host site.

Where do we go from here?

Héctor

I think, you’re using GoDaddy as your hosting, so you need to login into your goaddy account and access the cpanel and then check for error logs or goDaddy hosting support for help accessing the php Error logs.

Once you’ll get the log, you will be able to find which plugin is causing the issue then you can disable the plugin by renaming it using FTP Client or File Manager from you hosting/Cpanel.

This is the error log I received from GoDaddy (I as not aware that my “host” is GoDaddy):

I hope this can help you direct me. I really appreciate your time, effort and patience.

This seems to access log, we need php error logs. Please check for error logs not for the access logs.

I have checked the CPanel in GoDaddy and that is the only error log I found.

Ok, You can open File Manager in the root(/public_html/) you might find the error_log file, you can open that file and check the error log.

I was able to access the error log and it is a very lengthy document. I don′t know if I can send you the file but I cut and pasted the entries prior and after the “PHP Fatal error”:

I don′t know if it is relevant, but the only event prior to the error was the automatic updating of the Gutemberg plugin.

I have been navigating uncharted (for me) waters. I hope this sheds some light.

Héctor

Maybe if I can somehow deactivate or remove the Gutemberg plugin without access to the webpage, it would solve the problem.

Dear Vijay: I tried deleting the Gutenberg and the problem was immediately resolved. The website is back online.

I never could have done it without your knowledge, guidance and, above all, patience in dealing with a senior citizen with minimal technical knowledge. In the process, I have gained knowledge which I hope can help me in the future.

Thank you again!
Héctor
