UBB.threads PHP Forum Software Community Forums Resources and Customizing How Do I? Fatal Error Message

Hi All,

After changing the email settings I am getting this error message when clicking the control panel tab.

Can someone assist with a fix please.

Fatal error: Uncaught TypeError: Cannot access offset of type string on string in /home/xxxx/public_html/forum/admin/dashboard.php:173 Stack trace: #0 {main} thrown in /home/xxxx/public_html/forum/admin/dashboard.php on line 173
