This change may produce PHP fatal error in some cases as URE Pro v. 4.47.2 uses some PHP functions available at PHP 5.4 only.

I recommend to revert installed URE Pro to the previous version – 4.47.1. You can get it from the same download page – scroll to “Previous versions” section and select version from the list. Just replace user-role-edito-pro folder with files from 4.47.2. There was no any changes in the used data format.
