'PHP Warning: mb_stripos() empty delimiter' caused by wp-cron.php

  • I am getting the following errors in my PHP error_log:

    [16-Jan-2013 22:05:58 UTC] PHP Warning:  mb_stripos(): Empty delimiter in .../wp-includes/functions.php on line 658
[16-Jan-2013 22:05:58 UTC] PHP Warning:  mb_stripos(): Empty delimiter in .../wp-includes/functions.php on line 661

    I compared the error log with the access logs, and found that these errors happen when the server POST‘s to wp-cron.php.

    What might be causing this? I did not get this error before upgrading to WP 3.5. I realize that this is only a warning, and I know how to silence it. I would just like to know what might actually be causing it. I think it might actually be causing wp-cron to fail, though no other errors are logged, because my site has not been automatically running the backWPup backups like it did before.

    Any advice would be greatly appreciated. ??

    P.S. I am using PHP 5.4, if that makes any difference.

    If you search Google with that error you will see that there are other people having the same problem.

    Okay, I just removed them. I am not getting the error now. But it did get logged several times last night.

    Actually, I am still getting the error. I just tried it in another browser. My browser was just using the cache.

    Okay, I think that I have fixed this. It was a problem with the PHP configuration on my server. I was using the mbstring.func_overload directive, and that was causing some problems. Once I set it to mbstring.func_overload = 0, everything works fine!

    Thank you for walking my through this! I am so glad to get this figured out!
