I am trying to: ... save some setting for WCFM and it doesn´t work. AI tells it might be because of this.
Link to a page where the issue can be seen: Sorry, no other link available than the frontend.
I expected to see: ... not so many PHP errors. 😉
Instead, I got: a WCFM sandclock icon and several error in the console and debug.log.

Hello. Thank you for contacting the Toolset support.
Thank you for sharing the information but the information you shared does not reprecent any actual bug and its deprecated notices and that does not break the program execution.
Maybe you can check with the WCFM support and check with them what is the root cause and if Toolset is really involved in that we will try to proceed further.
