    Hi @brightblackafrica.,

    By any chance if you have written any mysql_query in your theme or plugin, kindly update it to mysqli_ extensions. Since mysql_ is removed in php 8. Else you can remove the direct query and try to use WP_Query method which will not be affected by php version upgrades.

    @karthickmurugan ,
    Please explain how this ” Else you can remove the direct query and try to use WP_Query method which will not be affected by php version upgrades.” can be done

    Hi.,

    Please check if any mysql_ code is found in your theme or plugins. Else this might be a hosting side issue with the mysql extension.
