Hi there,

An error like this can come from plugins as well as themes, or even custom functions.

I’m assuming it’s a plugin in this case, as GeneratePress doesn’t have any errors like this. Does it go away if you deactivate your plugins?

Thanks – you´re right. Got the plugin. Thanks and sorry for opening this thread.

No problem! Glad I could help 🙂
