Call to a member function render()

Hello,

Please access Wp_option in your database and then delete all the entries that start with ai1ec in this table.

Then reactivate your calendar plugin.

Thanks

Tried deleting all the entries that start with ai1ec in wp_options table. But still no luck. Can’t access admin because of this
PHP Fatal error: Call to a member function render() on a non-object in /var/www/*/*/wp-content/plugins/all-in-one-event-calendar/vendor/twig/Environment.php on line 300

Hello potasiyam,

I thing that error is occurred due to plugin conflicts. please refer to below link for checking plugin or theme conflict.

I got the same problem. I usually don’t work on the production site, but in a copy in localhost where i set the domain https://www.site.it in /etc/hosts to 127.0.0.1.

Locking with:
SELECT * FROM wp_options WHERE option_name LIKE ‘%ai1ec%’;

Some options like ‘ai1ec_current_theme’ have inside a full path. If you delete that options everything will be replaced at the first site refresh and everythings will work.

Maybe the developer can study a better method to solve.

At the moment i have no more error and i have deleted from wp_options table the follow options: ai1ec_current_theme, ai1ec_admin

define(‘WP_DEBUG’, true)
broke ai1ec plugin js.

What do you mean?What do you see in PHP error log?
