aaP_hk2263247 Thanks for your support.
I downgraded the Ubuntu version from 24.0 to 22.0 and successfully reinstalled PHP 8.3 and mbstring.
Thank you!

    I have the same issue in PHP 8.3:

Make sure that you run '/www/server/php/83/bin/phpize' in the top level source directory of the module

mbstring.sh: line 48: ./configure: No such file or directory

    I solved it by doing this:
    Install imagemagick first then fileinfo and finally install mbstring.

    In the latest 8.3 PHP version of aapanel, you can't install mbstring without installing imagemagick and fileinfo first.

    I discovered the problem!
    It's "autoconf" that is not installed on the system.
    Just run: "sudo apt-get install autoconf" and that's it.

    hi team, can you help me about this?
    Aapanel showing PHP 8.3.12 with some extension but phpinfo() show different
    the result is in my laravel app, showing error mb_strcut() which is with extension mbstring (that already installed in aapanel, but when in app & phpinfo it doesnt installed yet


      aaPanel_Kern
      its installed already in aapanel, but in phpinfo showing different. no mbrstring showed and show 8.3.10 instead not 8.3.12 same as aapanel info


          Hi, can you give us your aapanel information? The server makes a snapshot backup first, if possible, please send it to kern@aapanel.com.
          It is recommended to fill in the following
          Post link:
          SSH IP address, account password and port:
          aapanel login link address and account password:

            So what is correct solution for this?

            Install imagemagick first then fileinfo and finally install mbstring.

            or

            Just run: "sudo apt-get install autoconf" and that's it.

              aaP_hk2263247 same here! mi entire WP site crashed after updating a plugin which needs mbstring to work... so I am with the plugin disabled till someone could spot the problem. I can't install that extension un php83!

              PS. sudo apt-get install autoconf didn't solve that, as I already had it installed (Debian12)

                  Hello, was the installation successful? Please check the installation log to see what went wrong. /tmp/panelExec.log

                    aaP_erikator imagemagick installed but fileinfo won't. while installing fileinfo, all the server down, even I can not login server via putty.

                    @aaPanel_Kern there is a bug in php 8.3 install fileinfo extension, all server collapsed.
