Mbstring is a non-default extension  This means it is not enabled by default  You must explicitly enable the module with the configure option   In case your php version is 7 0   sudo apt-get install php7 0-mbstring  sudo service apache2 restart   In case your php version is 5 6   sudo apt-get install php5 6-mbstring  sudo service apache2 restart

Under Windows   WAMP there doesn t seem to be any php mbstring dll dependencies on the GD2 extension  the MySQL extensions  nor on external dlls libs   deplister exe ext php mbstring dll  php5ts dll OK MSVCR110 dll OK KERNEL32 dll OK   deplister exe ext php gd2 dll  php5ts dll OK USER32 dll OK GDI32 dll OK KERNEL32 dll OK MSVCR110 dll OK   Whatever php mbstring already needs  it s built-in  statically compiled right into the DLL       Call to undefined function mb detect encoding     This error is also very specific and deterministic     The function mb detect encoding   didn t fail because php gd  php mysql  php mysqli  or another extension was not loaded  it simply was NOT found   I m guessing that all the answers that are reported as valid  for Windows   WAMP   that say to load other extensions  to change php ini extension dir paths  if this one was wrong to begin with  NO extensions would load   etc  work more due to a  un-commenting the extension   php mbstring dll line  or b  restarting Apache or the computer  for changes to take effect    On Windows  most of the time the problem is that php mbstring dll is either    Blocked by Windows  Unblock it by right-clicking it  check Properties  Or PHP can t load php mbstring dll due to another version getting loaded  e g   from some improper PHP DLLs install into C  Windows system32   some version mismatch  missing run-time DLLs  etc  Check Apache s and PHP s error log files first for clues    More in-depth answer here  Call to undefined function mb detect encoding

I had the same problem with Ubuntu 17  Ispconfig was not processing the operations queued of any kind and also the server sh command was not working  I checked and the running PHP version after the OS upgrade was 7 1 so the solution was to type   apt-get install php7 1-mbstring   and now is everything ok

The problem could also be that Apache can t find php ini If you set PHPIniDir incorrectly  Mine was set to  PHPIniDir  c  php7  But  the folder is actually just  php  The clue was viewing phpinfo   Which showed  Configuration File  php ini  Path C  windows
