Hi,
I just updated both WP and X for the latest versions. When the updating process was done, my website crashed on every page and I received this erros in every page:
Notice : Undefined variable: content in /home1/mepre687/public_html/wp-content/plugins/cornerstone/includes/classes/element/class-element-front-end.php on line 104
I tried to activate/deactivate every plugin one by one and it did not work. I also tried to put “false” in the wp-config folder but it also did not work.
I used a backup version and then I reinstalled the last updates of WP and X. It worked, however some of the pages are not showing, for example:
This page is okay: https://meprepara.com.br/
This page is not showing: https://meprepara.com.br/curso-online/
Could you please help me?
