Problems creating pages

I have upgraded a previous J3 site to J4.2.4 with PBCK 2.17.0 and have 2 problems.

1. - when I try to add horizontal tabs to a page and save it, I immediately get a BITNINJA message from my host saying my request has been blocked. I then need to delist before I can re-enter the site. The article has been locked with no update applied.
2. - when I try to save any article AS A PAGE, I get the same effect, locked out with a BITNINJA message. This happens on any article.

Can you help please ?

Hi
this is something that you must check with your host provider, because the request is blocked on the server
I can not do anyting by my side here, your host provider must check that and tell you why it is blocked. It could be due to "mod_security"

let me know

Hi Ced

I contacted my host, and eventually they disabled the specific rule in BitNinja WAF for the domain. This fixed the problem.

thanks
