I get the following message after trying to update the plugin:
Fatal error: Uncaught Error: Call to undefined function trailingslashit() in /var/www/prilla.nu/public_html/wp-includes/class-wp-textdomain-registry.php:103 Stack trace: #0 /var/www/prilla.nu/public_html/wp-includes/l10n.php(784): WP_Textdomain_Registry->set(‘default’, ‘sv_SE’, ‘/var/www/prilla…’) #1 /var/www/prilla.nu/public_html/wp-includes/load.php(1401): load_textdomain(‘default’, ‘/var/www/prilla…’, ‘sv_SE’) #2 /var/www/prilla.nu/public_html/wp-includes/load.php(278): wp_load_translations_early() #3 /var/www/prilla.nu/public_html/wp-settings.php(74): wp_maintenance() #4 /var/www/prilla.nu/public_html/wp-config.php(92): require_once(‘/var/www/prilla…’) #5 /var/www/prilla.nu/public_html/wp-load.php(50): require_once(‘/var/www/prilla…’) #6 /var/www/prilla.nu/public_html/wp-blog-header.php(13): require_once(‘/var/www/prilla…’) #7 /var/www/prilla.nu/public_html/index.php(17): require(‘/var/www/prilla…’) #8 {main} thrown in /var/www/prilla.nu/public_html/wp-includes/class-wp-textdomain-registry.php on line 103
How do I resolve this?
The site goes back to normal after about 10 min. but I can’t update WordPress or any plugins.
