If that resolves the issue, reactivate each one individually until you find the cause. * If that does not resolve the issue, try switching to the default theme for your version of WordPress to rule-out a theme-specific issue (theme functions can interfere like plugins). * **Without Dashboard Access** * Try [manually resetting your plugins](https://codex.wordpress.org/FAQ_Troubleshooting#How_to_deactivate_all_plugins_when_not_able_to_access_the_administrative_menus.3F)( no Dashboard access required). If that resolves the issue, reactivate each one individually until you find the cause. * If that does not resolve the issue, access your server via [SFTP or FTP](https://codex.wordpress.org/FTP_Clients), or a file manager in your hosting account’s control panel, navigate to `/wp-content/ themes/` and rename the directory of your currently active theme. This will force the default theme to activate and hopefully rule-out a theme-specific issue ( theme functions can interfere like plugins). * — * If neither of those worked, then it could have been a fault update that is causing this error. In that case try [downloading WordPress](https://wordpress.org/download/) again, access your server via [SFTP or FTP](https://codex.wordpress.org/FTP_Clients), or a file manager in your hosting account’s control panel, and delete then replace your copies of everything except the `wp-config.php` file and the `/wp-content/` directory with fresh copies from the download. This will effectively replace all of your core files without damaging your content and settings. * Some uploaders tend to be unreliable when overwriting files, so don’t forget to delete the original files before replacing them. * Thread Starter [fedesr](https://wordpress.org/support/users/fedesr/) * (@fedesr) * [9 years, 11 months ago](https://wordpress.org/support/topic/help-me-errors-on-pluggablephp-and-postphp/#post-7453696) * In any two cases (with dashboard) have a same problem… * In either case the same problem occurs * I tried to reinstall wordpress from the menu updates but not solved * Any ideas? database? * [Matthew](https://wordpress.org/support/users/kidsguide/) * (@kidsguide) * [9 years, 11 months ago](https://wordpress.org/support/topic/help-me-errors-on-pluggablephp-and-postphp/#post-7453772) * So you disabled all your plugins and switched to a different theme to see if that would solve it? * Thread Starter [fedesr](https://wordpress.org/support/users/fedesr/) * (@fedesr) * [9 years, 11 months ago](https://wordpress.org/support/topic/help-me-errors-on-pluggablephp-and-postphp/#post-7453798) * Hi again! * I could solve the problem… * The wp-config.php had a UTF-8 coding … I changed it to ANSI and solved the problem… * Tnx to all! * [ryanchanel](https://wordpress.org/support/users/ryanchanel/) * (@ryanchanel) * [9 years, 7 months ago](https://wordpress.org/support/topic/help-me-errors-on-pluggablephp-and-postphp/#post-8349909) * @fedsr you are a genius!
