Please upgrade to WordPress 5.0 which supports PHP 7.3. Please also make sure that your environment has either MySQL 5.6+ or MariaDB 10+ installed.

Website works. On php 7.2 i get access to wp-admin but i can’t go to the pages page. It has an error log about mysql connect… php 5.6 ??? It used to work fine with php 7.1 could it be super cache or another plugin? * I was updated to wordpress 5.0.2 - This reply was modified 7 years, 5 months ago by [djusstattoo](https://wordpress.org/support/users/djusstattoo/). - This reply was modified 7 years, 5 months ago by [djusstattoo](https://wordpress.org/support/users/djusstattoo/). * [Robert Anderson](https://wordpress.org/support/users/noisysocks/) * (@noisysocks) * [7 years, 5 months ago](https://wordpress.org/support/topic/wp-admin-causes-error-log-on-certain-functions-when-using-php-7-3/#post-11038794) * This may be a plugin or theme conflict. Please attempt to disable all plugins, and use one of the default (Twenty*) themes.

That wp-db.php is out of date. But its in wp-includes. * public_html/wp-includes/wp-db.php:1564 * load.php wp-db.php wp-settings.php admin.php and others are all in the wordpress 5.0 folders. They are using mysql-connect which is depreciated. I don’t see how desactivating plugins would help with wordpress core files… all the errors listed come from wordpress .php files. And it’s exactly whats not working is wp-admin… the site works well no error log or plugin or theme conflict. It’s blocking wordpress back end editor with the mysql connect function. Again website is fine just wp- admin is innacessable. with php 7.2 /wp-admin/ is accessible juste the pages and extensions pages that block the error log higher. With php 7.3 all of wp- admin is blocked and error logged. * Thread Starter [djusstattoo](https://wordpress.org/support/users/djusstattoo/) * (@djusstattoo) * [7 years, 5 months ago](https://wordpress.org/support/topic/wp-admin-causes-error-log-on-certain-functions-when-using-php-7-3/#post-11067345) * [@noisysocks](https://wordpress.org/support/users/noisysocks/) No php works desactivated all plugins and running twentyseventeen freshly restored, tried setting cachesetting to false in wp-config.php the WP_USE_EXT_MYSQL function is not defined. i renamed .htacces i renamed themes folders i renamed plugins folder to desactivate all i went to phpmyadmin in options table set to twentyseventeen theme and a:0:{} plugins nto desactivate all plugins. went back and forth in php versions and its really stuck in error mode. */wp-admin doesn’t work but website works but is displaying different themes on different pages. * Thread Starter [djusstattoo](https://wordpress.org/support/users/djusstattoo/) * (@djusstattoo) * [7 years, 5 months ago](https://wordpress.org/support/topic/wp-admin-causes-error-log-on-certain-functions-when-using-php-7-3/#post-11075708) * [@noisysocks](https://wordpress.org/support/users/noisysocks/) The problem was MySQLI php modules where not activated. We had to activate: nd_mysqls * Plus caching was being a part of the problem even if plugin was desactivated. It would still load error message page as cached. Thats why reverting back to previous php versions would not work it would always serve the error message from cache. * Even if /wp=admin didn’t work, the website was still ok and running probably caching was saving it. * We had to access [https://tatouagecalypso.com/wp-admin](https://tatouagecalypso.com/wp-admin) with url parameters to bypass caching bu adding [https://tatouagecalypso.com/wp-admin/?d=asdd](https://tatouagecalypso.com/wp-admin/?d=asdd) or just /?. * So php modules have to be activated website now runs pnp 7.3 with nd_mysqls activated in php options in Cpanel.
