  • Hi digiman55,

    Based on the error log you shared, it seems like there is an issue with the WordPress core files, specifically with the trailingslashit() function.

    To resolve this issue, you can try the following steps:

    – Replace core files: Download a fresh copy of the latest WordPress version and replace all files except the wp-content and wp-config.php file in your WordPress directory. This will overwrite any corrupted core files and ensure the trailingslashit() function is available.

    – Check for Plugin or Theme Conflicts: If the issue persists after reinstallation, try temporarily renaming the plugins’ directory to something like plugins_backup. This will deactivate all plugins. If the dashboard becomes accessible, rename the directory back to plugins and reactivate plugins individually to identify the problematic plugin.

    Try this out, and let me know how it goes.
