I’ve tried to update my 3.0.5 blog to 3.1.1 and couldn’t do it. Still getting the error
Fatal error: Call to undefined method stdClass::add_query_var() in public_html/ambnotes/wp-includes/taxonomy.php on line 318
Please, can somebody help me? Tried to change theme to Twenty Two. Tried to deactivate all plugins and after deactivating did upgrade. Getting this error.
I don’t know what to do. Actually, I never used taxonomy in my blog so, I never changed anything here. May be here is my mistake? Or not?
Please, help me?
Same problem I’ve had after I’ve tried to upgrade to 3.1. Have two blogs and on both of them getting the same error
