14,142 PointsHow to fix wordpress debug php notice: undefined index 00 in locale.php?
I have debug logging turned on on my wordpress site and when looking at the file I see the following notice coming up a lot.
[31-Jan-2016 22:56:52 UTC] PHP Notice: Undefined index: 00 in /var/sites/b/mysite.com/public_html/wp-includes/locale.php on line 287
From what I can gather it is a call to a function which is trying to process a month with a value of 00 but I'm not sure.
I am wondering if anyone has had this problem or where I am best looking in trying to fix it as it is clogging up the file every day!
Thanks Gary

14,142 PointsUnfortunately nothing specific, at the moment I have the easy pie coming soon plugin active and if I visit the site I still get the error (this happened before the plugin was active as well).
All of the dates within the posts table of my database have correct month values, everything is between 01 and 12, this is really bugging me :(

16,593 PointsHave you disabled every plugin, switched to a fresh theme, or even tried setting up a boilerplate site with the theme/plugin setup to see if that changes?

14,142 PointsUnfortunately I can't for the moment as its a business site going live in a few days, are there any functions or such like that could be causing the problem if it isn't anything to do with post publish dates?
Thank you!

14,142 PointsOk I had a try with some of the plugins and have found the culprit! It is the SEO Ultimate plugin that is causing this error! Thank you for your help I will get in touch with them!
Gary Stewart
14,142 PointsFor future reference of those who find this issue with the SEO Ultimate plugin, the plugin (thankfully) features a reinstall function within the settings, a quick reinstall and all these PHP notices are no more!
Hope this helps someone else! Thanks!

14,142 PointsHi Luke, thank you for your tip, unfortunately after looking at my database it seems that all of the dates within the posts table look correct.
Do you have any other ideas?
Thanks Gary

16,593 PointsDo you have any more details as far as what pages this happens on ?

The above article details it a little more, looks like it is a known wont-fix issue as it pertains to incorrect data. Do you by chance have a month that is outside of the 1-12 range? (ie 13)
