Hi the problem seems to be that some of those plugins include official wordpress files too soon. So when this plugin tries to update the sitemaps it can’t find the functions from those files.
I’ll see if I can find a fix for this, so just deactivate the plugin for now and check back when there’s a new update!
Just notice, this error showed me also when I press “purchase” in checkout with plugin Easy Digital Download.
Exact same error? Strange, and that’s totally weird that my plugin runs on a purchase button!
Thank you for notifying me, I’m gonna have to look this up and add some fixes during the week. Btw can you post a link to that plugin?
Yes, it was the same error. Here is link https://github.com/easydigitaldownloads/Easy-Digital-Downloads
I think (not sure now) I got this error also using gravity forms – while create post using this form and some other post plugins too.
So after last update, it looks like plugin is more mature 🙂 Now works excellent.
Thank you for that.
Yeah it kinda ended up in a total makeover. Had way to many issues before, and found even more when I started to look up what you reported here.
No problems, glad it works now 🙂
