Site Integrity – Critical issues – Checksum mismatch

Hello @ferda2 ,

Thank you for getting in touch with us.

We tried to install the plugin WP Cerber to our site to reproduce the issue, but the plugin is closed and not available for download in WordPress plugin repository because of security issue. See the screenshot.

Is the plugin still maintained by the author? Where can we download and install it?

Kind regards.

Hello @ferda2 ,

Thanks. We are going to check it out and keep you updated once the troubleshooting is done.

Best regards.

Hello @ferda2 ,

We installed WP Cerber plugin and there is no errors reported by WP Cerber plugin.

Where did you see the report? Could you send us a screenshot of the report please?

Additionally, the problamtic code line of the file wpvivid-backup-restore-page-display.php isn’t included in the report. So, what is the problematic codes? We don’t even know what is the security issue.

We would appreciate it if you could send us these information.

Kind regards.

Hello @ferda2

Thanks for your update. We are going to check it out and get back to you shortly.

All the best,

Hello @ferda2

In the information you provided, for example:

/wpvivid-backuprestore/admin/partials/wpvivid-backup-restore-page-display.php

This is a PHP file of WPvivid Backup Plugin.

But we are not sure what the following information means:

Checksum mismatch

New file

High 124 KB 12. 1. 2023, 18:44

Does it mean that the file has been modified from the file that is distributed by www.remarpro.com?

If so, it is recommended to reinstall WPvivid Backup Plugin and see if that solves the issue.

If that does not solve the issue, then would you please check with the developer of WP Cerber and see whether they could provide more details about the report?

All the best,

I uninstalled and then reinstalled and everything is fine. Thank you.

Hi @ferda2

Great. Glad the issue is resolved!

All the best,
