Wonderful—thank you very much!

I could only find a way to add those lines to all pages and the "Group by" button still doesn't seem to work, but regardless your suggestion fixed the major issues ...

Christian,

Could there be any other suggestions you may have to fix this, or maybe we can not use Bibbase on our site and have to look for other alternatives? Thank you!

Thanks for your prompt and detailed responses. 

As you can tell, I am using the common Divi theme on top of Wordpress for the pages. I have not changed any of the JS settings, and am not able to find those either. 

I had "nocache=1" and removed that now, but the issue does not seem to be related to that. 

Same here, and on all browsers. I wonder how long the page has been like that and we did not notice!!
