    OK - it seems Gallery has not been updated in a long time and is not compatible with 2.5.8??? The controls to delete / order images have disappeared... Just been forced to move from 2.1.10 to 2.5.8 due to a forced server upgrade to PHP7 which 2.1.10 does not work on... Now the gallery system in this site is a total mess... Anyone any ideas on a resolution????

      It looks like Gallery requires php-mbstring Enabled.

      http://php.net/manual/en/mbstring.installation.php has the following to say about php-mbstring

      mbstring is a non-default extension. This means it is not enabled by default. You must explicitly enable the module with the configure option.

      So maybe your new PHP7 install needs to have php-mbstring enabled?
        If I help you out on these forums I would be very grateful if you would consider rating me on Trustpilot: https://uk.trustpilot.com/review/andytough.com

        Thanks Andy - will have a look into it.
