interactive book

The interactive book content is not responding due to the following error: call to undefined function str_contains(). This occurs only when re-entering the content. According to my research, this is due to the PHP version, which needs to be 8, as I have Moodle version 3.10 and do not have that version of PHP. I would appreciate your prompt attention to this matter. Thank you very much.

I use interactive books fairly frequently, and I have included Course Presentations within an Interactive book before. It seems like it's no longer possible to do this though, the option under the "add content" menu no longer includes course presentation. Is there a fix for this or was it an intentional removal for some reason?

I created a resource using the "Information Wall" content type. I need the search bar within the resource so that learners can type a keyword into the search bar and find what they need within the resource.

However, after I created the resource and added it to the LMS, I do not see the Search bar. Not sure why?

Any help is appreciated!!!!
