Hello charrame,
Thanks for contacting us! There may be some information lost in translation, but I believe I understand you correctly.
Depending on you theme, I think you can get the slider to appear by changing the template on the Event Settings > Display page in WP-Admin. If you change it to ‘Default Page Template’ or something similar I *think* the slider will appear, but I’m not sure.
I’m not sure why the border is showing on the blog menu item, that should be out of the realm of our plugin though. Did you add a class to the link in the menu?
Does this make sense? Let me know if this doesn’t work for you.
Cheers!
