Hello. These are only Strict warnings, that doesn't have any effect on program. We fixed this issue in version 2.0.20, so you should upgrade.

Thank you.

When I would like to do the upgrade the error message occurs, that your server is not available at the moment and that I should try it later. This message occurs since two or three days.
