ragingeagle – until you get to the bottom of it I would ask your hosting provider to block those ip addresses in your .htaccess file. Doing so won’t even let them get as far into your system to be blocked by WpCerber.

good luck…

DITTO please!

Is there any way to filter out these errors (or ignore them) as they’re clogging up the activity log with unimportant information.

This is a bug introduced in the most recent WordPress update. The plugin author is aware of the issue and promised a fix soon (in another thread). There is a workaround but it involves modifying one of the WP core program files. My advice for now is just to live with it until the plugin is updated. Or temporarily re-enable the wp-login until the plugin is updates.

Cheers!

I’m having the same issue. Exactly where do I modify the logout URL in WPCerber to include ?loggedout=true ? I’m having trouble finding the setting.

Thank you!

Thank you James! I found them in a table with the oddly named prefix “wpxj_”

I have a similar problem with the Rascals Epron theme, in that I get a non-css formatted front page of my website along with “404 error” mixed in with the non formatted text. It’s not a big deal, I just switched Cerber to use a generic 404 error page in the settings. I’m more curious than anything about how to get the theme’s custom 404 page to appear.

Great! Which specific wpcerber .php file had the white space in it?

P.S. I’ve been bitten by that bug in my own programming so many times I can’t count!

Generally, it’s been my personal experience that the “Warning: Cannot modify header information – headers already sent by (output” is the result of one or more white spaces at the beginning of the PHP code. For example if the code started with a blank line, or even a space before the php tag in the code:
<?php>
That will cause this error. Somewhat unlikely int his case since Gioni is a excellent coder. But something may have happened to the plugin code upon upload. He would be best to address the issue.

Ok, so do I just install 4.8.2 now and I’ll be able to do that? As I said I had to delete the 4.8.1 plugin in order to regain admin access to the site.

Love this plugin!

You have to drop the four Cerber tables AND delete all the fields I laid out in the wp_options table in your WordPress database.

login to your site’s Cpanel. PhyMyAdmin is located there.

Hope this helps!

Great! Thank you again…

This is what I had to do when I had weird trouble with the plugin. It does store data in your WordPress database, in a few locations. I use cpanel and PHPMYadmin to do the following (backup up your database first.)

Disabled and deleted the WPCerber plugin files.
PhpMyAdmin & opened the WordPress database for the site.
I deleted (dropped) the four cerber tables at the top (but that wasn’t enough)
Sorted the “wp_options” table by field name.
Deleted all “_cp entries”
Deleted all entries starting with “cerber”
Reinstalled plugin
Working…

Try some basic troubleshooting steps.

1) Get your ip address https://get.youripfast.com/
2) CALL your hosting provider and ask them if THEY have blocked your ip for any reason.
3) Rename the cerber plugin folder wp-content/plugins/wp-cerber to wp-cerber.bak (this will disable the plugin.) You can use filemanager in cpanel to do this.
4) Now try to login. If disabling the plugin allows you to login now then it’s wp-cerber’s problem, otherwise it’s something else.
