i want to install payumoney extension i had uploded every thing while installing i m getting this error
what should i do...

Extension you want to install doesn't support OC 2.3 completely. Install our OpenCart 2.3 Compatibility Fixes extension and try again. Should work. Don't forget to uninstall your extension before that and check access/modify permissions for your group.
