This problems have been around 2 years now and on every new update or wordpress install/ project I have to go manually and quote the assumed variables correctly in the plugin core file.
Our company policy demands clean code, no Notices, readers : please dont suggest turn error reporting or dubug off
Notice: Use of undefined constant XCloner - assumed 'XCloner' in \www\wp-clean\wp-content\plugins\xcloner-backup-and-restore\xcloner.php on line 28
Could author please fix this once for all?
Thanks for the best backup plugin I ever used so far!
