I'm troubleshooting a client site on GoDaddy and I have this strange issue that when I try and run update_post_meta the server throws a 500 error accompanied by this error message: Fatal error: Call to undefined method Redis_Object_Cache::incr2()

If I change the meta key the 500 error stops.

I found a solution and will add an answer but I'm still not sure why this happens.

I was able to find a solution by following the advice in this article (https://www.godaddy.com/community/Building-and-Managing-a-Website/fatal-error/td-p/31814):

Open your hosting account, go to File manager and access this folder: wp-content Rename this file object-cache.php to object-cache-OLD.php

As a developer I don't know how to prevent this for future clients without a greater understanding. Comments and new answers welcome.

  • This sounds like an issue limited to managed GoDaddy hosting, so it would be best to inquire with them to find out how the issue can be proactively stopped. Commented Jun 28, 2017 at 1:24
