[RedHair]

Hi every one,

I'm from Vietnam, my website have a problem about drop-in plugin object-cache.php.

I can't call to support mobile phone number in vn.godaddy.com.

My problem details

Warning: Class __PHP_Incomplete_Class has no unserializer in /home/content/xxxxx/05/3230xxx/html/xxxxxxxx/object-cache.php on line 520

I flush cache, and it disappear, but after little time, it appear again.

If any support here please give me advice, give me your email or contact me at hddung89@outlook.com to get more information.

Thanks you.

Sorry for my bad english.

It only a warning, not an error.  If it doesn't impact the site operation, you can safely ignore it.  Wordpress sites commonly have quite a few of these.  As long as everything is working, you're probably ok.

Are you noticing specific bad behavior when you start to see this message?  Where is the message appearing?
