I've just upgraded a site to K2 2.10.0 and the site has imposed a Category item layout count maximum of 100, ignoring the settings that were working fine before.

I've turned on pagination so that all the entries can be seen, albeit over two pages, but it's not what the client wants.

If you could give me some indication as to how to resolve this, that would be great.

Thanks.

Unfortunately there is no option in 2.10.2. Please add this option. Thank you!

Yes, I did and I am very thankful that you gave this hint. I didn't find it before and would like to be update-safe.
Thanks for keeping up the good work. I am using K2 for so many years now and never thought about switching to something else.
