WP Toolkit Error

What kind of “WP Toolkit” do you mean? Know the term from various server management, such as Plesk or cpanel. If you have questions about this, better contact the support of your hosting.

What is the exact message at login? It won’t just say “broken”. Take a look at the error log – there you should be able to identify the cause of technical errors.

@threadi found this message in broken site;

‘Site data was refreshed and stored in cache. The site is now marked as broken since WP Toolkit could not establish connection to it due to the following issue: Fatal error: Array and string offset access syntax with curly braces is no longer supported in /home/filename/public_html/wp-includes/blocks/index.php on line 2 Error: There has been a critical error on this website. Learn more about troubleshooting WordPress. There has been a critical error on this website.’

This is a PHP compatibility error. Which WordPress version are you running there?

If it’s a version 5.9 or newer, this could also be a follow-up error from an outdated plugin. You could rename the plugin directory via FTP (e.g. from wp-content/plugins/ to wp-content/plugins.backup/) and see if that solves the problem.

Of course, the error message is also not complete. In the above debug log should be more visible than just this excerpt.

Thanks @threadi ! I rolled back the PHP version from 8.1 to 7.4, and the site is now working. However, there’s still a plugin conflict causing a critical error, so I need to identify the plugin responsible for the issue.

Oh unfortunately, this method doesn’t work on some of my subdomains (broken sites). however I was able to access the dashboard, it appears to be messy. Could you help me with this?

You should find more detailed information about the error in the error log. Unfortunately, you can’t do anything with the information up to here.

Thank you, mate! I appreciate your response. I was able to fix the broken sites by removing suspicious codes from the directory /wp-includes/blocks/index.php. However, I’ve been encountering issues in wp-admin. I will address this in another thread so that I can close this one. Thanks a lot!

You describe that you have customized problematic code from WordPress core. You should NEVER do that. This way no one could tell you why your WordPress works the way it does for you. Moreover, this would be reset at the next update or when you reinstall your WordPress.

The real cause for the error will surely be somewhere else – not in the code you mentioned. What exactly did the error log say about this?

@threadi actually, this issue pertains to the main domain, which initially broke but returned after server expansion. however, for some reason, the subdomains remain broken (as seen in this screenshot: https://imgur.com/HEuS86H), accompanied by this error message from the log: https://imgur.com/Jq6HWGL.

to address this, I have attempted several potential solutions, including:

• checking the database
• verifying file permissions
• disabling plugins and themes
• checking PHP compatibility

as a result, only one subdomain was fixed by downgrading the PHP version from 8.1 to 7.4.

based on the error message I got from wp toolkit;
“The site is now marked as broken since WP Toolkit could not establish a connection to it due to the following issue: Fatal error: Array and string offset access syntax with curly braces is no longer supported in public_html/mywebsite/wp-includes/blocks/index.php on line 2 Error”

I investigated the contents of the index.php file and found this: https://imgur.com/krvq0oI

upon comparing it to the working site, it looks suspicious for me. so I removed that code, and refreshed the wp toolkit who is now working.. BUT unfortunately, another issue appears in the /wp-admin; the dashboard is not displaying properly (https://imgur.com/UjjpEjZ)

Your site is hacked. This can be seen by the strange code in the index.php. You can consider the whole project insecure and I would recommend to delete it completely. If you have an older backup, you could use that.
