Plugin issue.

[ghost]

Slapper_v1.3.3.phar

[ghost]

why it causes error?

@ExaSonit Because the plugin needs to be updated to match all the changes in v1.1, as do many plugins that are suddenly spitting out errors.

In the future, test WITHOUT plugins before submitting a report. If the issue disappears, it's a plugin and the devs here are not going to do anything but tell you it's a plugin issue. so you would be wasting everyone's time opening a bug report here; you would need to contact the Plugin developer.

yes, now it works don't worry, thanks for support
