Title: Fatal error while activating all plugins Last modified: July 22, 2023 --- # Fatal error while activating all plugins * [hollenberg0752](https://wordpress.org/support/users/hollenberg0752/) * (@hollenberg0752) * [2 years, 10 months ago](https://wordpress.org/support/topic/fatal-error-while-activating-all-plugins/) * Hello, as I did not find any answer in the forum, can anybody help on fatal errors with statistics plugins? I had WP Statistics on my blog, but then deactivated it, because I wanted to try another one. Anyway, when I re-installed it, I received a fatal arror message. Then I deactivated it and tried to install three other statistics plugins such as, but every time I received the same message: Fatal error. My internet provider said that PHP and WordPress – from their perspective– are working all right. Then I tried the error logfiles and found huge lists. They pointed out that the error messages come from calling a file, which is …/ plugins/wp-excel-cms/public/wp-excel-cms.php. They said I should delete this WP excel plugin, which I did. But still I am receiving fatal errors on all statistics plugins I try to install. The error message in WordPress is: * Fatal error: Uncaught mysqli_sql_exception: Duplicate entry ‘2014-10-19’ for key ‘unique_date’ in /mnt/web006/a3/88/51314188/htdocs/WordPress_01/wp-includes/ wp-db.php:2056 Stack trace: #0 /mnt/web006/a3/88/51314188/htdocs/WordPress_01/ wp-includes/wp-db.php(2056): mysqli_query() #1 /mnt/web006/a3/88/51314188/htdocs/ WordPress_01/wp-includes/wp-db.php(1945): wpdb->_do_query() #2 /mnt/web006/a3/ 88/51314188/htdocs/WordPress_01/wp-admin/includes/upgrade.php(3032): wpdb->query()# 3 /mnt/web006/a3/88/51314188/htdocs/WordPress_01/wp-content/plugins/wp-statistics/ includes/class-wp-statistics-install.php(109): dbDelta() #4 /mnt/web006/a3/88/ 51314188/htdocs/WordPress_01/wp-content/plugins/wp-statistics/includes/class- wp-statistics-install.php(63): WP_STATISTICS\Install::table_sql() #5 /mnt/web006/ a3/88/51314188/htdocs/WordPress_01/wp-content/plugins/wp-statistics/includes/ class-wp-statistics-install.php(35): WP_STATISTICS\Install::create_table() #6/ mnt/web006/a3/88/51314188/htdocs/WordPress_01/wp-content/plugins/wp-statistics/ includes/class-wp-statistics.php(332): WP_STATISTICS\Install->install() #7 /mnt/ web006/a3/88/51314188/htdocs/WordPress_01/wp-includes/class-wp-hook.php(303): WP_Statistics::install() #8 /mnt/web006/a3/88/51314188/htdocs/WordPress_01/wp- includes/class-wp-hook.php(327): WP_Hook->apply_filters() #9 /mnt/web006/a3/88/ 51314188/htdocs/WordPress_01/wp-includes/plugin.php(470): WP_Hook->do_action()# 10 /mnt/web006/a3/88/51314188/htdocs/WordPress_01/wp-admin/plugins.php(193): do_action() #11 {main} thrown in /mnt/web006/a3/88/51314188/htdocs/WordPress_01/ wp-includes/wp-db.php on line 2056 * Can anybody help? * Best regards Viewing 3 replies - 1 through 3 (of 3 total) * Plugin Author [Mostafa Soufi](https://wordpress.org/support/users/mostafas1990/) * (@mostafas1990) * [2 years, 10 months ago](https://wordpress.org/support/topic/fatal-error-while-activating-all-plugins/#post-16914332) * Hello, * Thank you for reporting the issue, can you please double-check that you are using the latest version of WP Statistics?

As I had the plugin de-installed and re-installed, I must have used the newest version, yes.
