PHP is listed as 5.6.40



% php -v

PHP 5.6.40 (cli) (built: Jan 14 2021 14:37:24)

Copyright (c) 1997-2016 The PHP Group

Zend Engine v2.6.0, Copyright (c) 1998-2016 Zend Technologie



SQL is 5.6.51


Which brings up a question --  does anybody know the latest version of PHP that is compatible  with this older version of the software (as part of my migration path)?

I would suggest the following

  • Make a full backup
  • update to PHP 8
  • upload a fresh set of files from your client area
  • upgrade from /admin/upgrade . If you have any issues please let us know.

The reality is, this is going to be the best way forward. It may be best to simply disable all 3rd party items and deal with upgrading those after you have a successful upgrade as most are likely to be outdated and wont work.
