New PHP Versions and Better Together Admin / Combination Discounts Admin

If you are using Better Together Admin (Zen Cart or osCommerce) and getting a log message that looks like this:

Only variables should be assigned by reference in YOUR_ADMIN/includes/xajax/xajax_core/xajaxPluginManager.inc.php on line 268

or this:

PHP Strict Standards:  Non-static method xajaxPluginManager::getInstance() should not be called statically, assuming $this from incompatible context in YOUR_ADMIN/includes/xajax/xajax_core/xajax.inc.php on line 269

Then please refer to the instructions for fixing this issue on the Better Together Admin help page.

The same instructions apply for Combination Discounts Admin.
