Long-time user of 4Images. Recently I set up my own local NAS and have successfully migrated over two of my WordPress sites, however, I am struggling to migrate over my 4Images site. While trying to troubleshoot the migration, I also tried to install a fresh copy of of 4Images, also to no avail. I'm obviously missing something. This is the error I'm getting on the new install. The install.php comes up, I fill in the information and I get this (password protected of course):
Fatal error: Uncaught Error: Call to undefined function safe_htmlspecialchars() in /volume1/web/4images/includes/db_mysqli.php:38 Stack trace: #0 /volume1/web/4images/install.php(234): Db->__construct('localhost', '4images', '***********', '4images') #1 {main} thrown in /volume1/web/4images/includes/db_mysqli.php on line 38
