Not working with custom category permalinks (infinite redirect)

I’m using the custom permalinks plugin(www.ads-software.com/plugins/custom-permalinks) on my site and I can’t make search & filter working. My site is: keto.hu/pinterest – here you can test it. For example: “https://keto.hu/kategoria/pinterest/?tag=nyers-huseves” this is where i can get with the Submit button.

My category permalinks are without “/category”.

Thank you if you could help!:)
