After activating the plugin, the following error appears:
Fatal error: Unparenthesized `a ? b : c ? d : e` is not supported. Use either `(a ? b : c) ? d : e` or `a ? b : (c ? d : e)` in /home/grupots/public_html/system/Theme/Theme.php(885) : eval()'d code on line 1273
If I deactivate the plugin the error disappears
