Undefined array key “delete”

Hi, which object cache plugin are you using?

… because that is where the warning is coming from.

Hey,

It’s WPEngine – same warning on multiple sites. I will see if i can find anything in object-cache.php

Best Regards,
Darko

When do you get the error exactly? Maybe test again after turning the WPEngine object cache off, temporarily…

Or you can try the development version https://downloads.www.ads-software.com/plugin/xml-sitemap-feed.zip ?? Let me know!

@ravanh – thank you! The issue is resolved in the development version. Good job!

Haha, no the original issue is not resolved, it just does not occur anymore. The dev version does not use transients in the same way. I suspect the WPengine object cache plugin will still throw a similar error under similar circumstances (when a transient is deleted).

Anyway, happy to hear my plugin is not involved anymore! ??
