    I had to rollback the latest update because I could not open posts.

    Everything worked until I tried to open a post, then I get an error 500.

    Rolled back and worked again.

    PHP Fatal error:  Uncaught Error: Call to undefined function mb_strpos() in /home/xxx/public_html/wp-content/plugins/asgaros-forum/includes/forum.php:1191

    Hello @sandgroper

    Which version of PHP are you using?

    Seems that the mb-strings module/extension is disabled or not installed on your PHP installation. Thats strange that this issue didnt happen before because those functions are used on other places as well since a long time already.

    Don’t know. Above my pay grade 🙂

    Would that show up in phpinfo.php? If so, where abouts.

    Did a screen search for it using CTRL+F but it didn’t show anything.

    The current line 1191 says strpos, not mb_strpos:

    $space_position = strpos($string, ' ', $length);

    Hello @sandgroper

    I released a new update and it should be fixed now. Using the mb_strpos function is fine, but it seems that not all servers have installed it. So I make a check first before deciding which one to use. 🙂

    Thanks. That fixed it.
