Anti-Spam error and plugin stopping search capability

Two things

As I could not get search to work on the listed site I went through all plugins to check the issue.

With your plugin activated search on the site would not work. De-activate your plugin and search works again.

Also when I re-activate your plugin I get this in your plugin dashboard:

)

Please can you advise
