I have used this product for several years and it works really well for us at MHB. I hadn't found the need to manage any of our post templates since our update to PHP 7 until tonight, and I found I got an "Methods with the same name as their class will not be constructors" error.
The fix was easy; I edited the file "includes/class_dm_posttemplates.php" by changing line 34 to read:
PHP Code:
function vB_DataManager_PostTemplates_f(&$registry, $errtype = ERRTYPE_STANDARD)
Thanks to DBTech for another useful product.
