Goodevening, can you help me please. When I try to upgrade a plugin I get the following message:
Notice: Trying to get property ‘ID’ of non-object in /var/www/vhosts/746192305.linuxzone149.grserver.gr/toypark.gr/wp-includes/class-wp-query.php on line 3965
Notice: Trying to get property ‘post_title’ of non-object in /var/www/vhosts/746192305.linuxzone149.grserver.gr/toypark.gr/wp-includes/class-wp-query.php on line 3967
Notice: Trying to get property ‘post_name’ of non-object in /var/www/vhosts/746192305.linuxzone149.grserver.gr/toypark.gr/wp-includes/class-wp-query.php on line 3969
I’ve tried it with 3 plugins.
Also can you tell me why Ajax filters do not work? I select them but they don’t work on the pages.
And last but not least, thank you for understanding. Because once I have uploaded the site you can give me 2 tips to make it faster?
Thank you!
