Error when inserting Power CMS content

webassist >> cms >> insert content from power cms

ERROR: Fatal error: Uncaught Error: Call to undefined function mysql_select_db() in C:\xampp\htdocs\allanbaumgarten\WA_Globals\WA_Globals.php:38 Stack trace: #0 C:\xampp\htdocs\allanbaumgarten\WA_CMS\WA_CMS.php(4): require_once() #1 C:\xampp\htdocs\allanbaumgarten\index.php(5): require_once('C:\\xampp\\htdocs...') #2 {main} thrown in C:\xampp\htdocs\allanbaumgarten\WA_Globals\WA_Globals.php on line 38

This is being done with MySQLi, and I have Version: 1.2.2 of Design Extender installed.

Also, I can't access the admin_cms folder in a browser. More errors: Fatal error: Uncaught Error: Call to undefined function mysql_select_db() in C:\xampp\htdocs\allanbaumgarten\WA_Globals\WA_Globals.php:38 Stack trace: #0 C:\xampp\htdocs\allanbaumgarten\admin_cms\index.php(6): require_once() #1 {main} thrown in C:\xampp\htdocs\allanbaumgarten\WA_Globals\WA_Globals.php on line 38

NOTE: This site was previously created years ago using MySQL and I'm going through and trying to update it to MySQLi now. What do I need to do to make PowerCMS work?

Thank you.

PowerCMS will not work with MySQLi yet. We will be updating Design Extender for MySQLi early next year. It will not currently work on php7.

I do all of my development on my local computer, using XAMPP. Currently, I have PHP version 7.1.9 installed. How can I, without losing all of my MySQL databases, revert back to version 6.x.x., or whatever will work with Power CMS?

Thanks.

You can use the "Export" option in phpMyAdmin to back up all of your data before reinstalling an older version.
