Hi Christoqh,
I have issued a new version to fix the headers already sent error you were getting. I tried to replicate the Elementor issue but was unable to figure out what overlay you were seeing — is it possible for you to take a screenshot and upload a link of it here so I can see exactly what you are looking at?
I will definitely look into adding a setting to remove the category base — that’s a good idea!
As my first plugin on www.remarpro.com I am happy you are enjoying my plugin. Please let me know if there is anything I can improve, I would love to get your review to a 5 star rating.
Thanks,
Zain
