WordPress Update 4.5.2 is now available. This is a security release for all previous versions and I recommend to update your sites immediately.
For more information visit the website:
Before you update the WordPress package, any PlugIn or the Theme, create a backup and save this on a secure place (Computer, external Harddrive, Cloud Drive, etc.). Follow the update instructions provided under the menu Dashboard -> Updates. After the update is completed make sure to create a backup of the new version. Also testing the new version!
If you have any question about the update, please contact me
