PHP-Warning-feof-fread-filling-error-logs-and-disc usage in cpanel

The error is quite clear - something in the wp-mbrxsmrs.php script is expecting a file to be open - the file is not open (either does not exist or permissions are wrong) so that line is failing.

I do not recognise that file - usually there is only one file in wp-content and that is index.php so this is probably a custom script that has not been written in a robust manner.

If you can post that script we can have a look to see what is going on.

@Julian is correct. The likely fix is simply to check file open return code + just return, if there's an open error.

More importantly though, this file looks highly suspect... as in potentially part of a hack...

The file name + location suggest this site might have been hacked.

Likely good if you have a WordPress Server Savant go through your site + clean up any suspicious looking files.

Thanks for helping.

Julian, I just downloaded the index php from wp-content. please find attached.

David, how can I do this?

That might be also why the bandwidth is so high suddenly?

Sorry I am not an expert in this kind of thing.
index.php

Nope, did not ask for the index.php I asked for the file that is actually causing the problem which if you look at the error message is this one
/home/qgzs8bjq/public_html/wp-content/wp-mbrxsmrs.php

However, having looked at the file you posted - you have been hacked.

That file contains malicious code you do not want on your site.

You need to get a WP guru in and clean your site - pretty much a certainty that there are other files that have been breached as well.

Sorry Julian,

here it is the file.

oh gosh, thats a tricky one with that hack I guess. Do you know were to start with that?
Would it be an option to restore the whole page?

Is this file something I just can get rid of?

Thanks
wp-mbrxsmrs.php

furthermore I have this error log alway coming up....
error_log

This file is also part of the hack.

This is not something we can help you with in this forum - you need someone knowledgable to come and look at your site and clean it.

Then you need to consult with someone about hardening your WP site - installing measures to prevent this sort of breach in the future.
