Dear~ the reply I pasted here, from this topic: https://wplms.io/support/forums/topic/dearhow-to-solve-this-https-prnt-sc-ttrj5e%ef%bb%bf/ Point 1: I can custom code on Blank Child Theme(for wplms 3.9.9 version) and can create a template that will show only students. 
What say? But filtering students using names will not be provided. On that page, only it will fetch your students from your site and show there

>>>Yes, please!     very appreciated:D  You can do custom code on Blank Child Theme directly :D Does student members page can be filtered by their "country" ,"the course they like"? (like every student has its own tags, maybe 5G, BIO, FOOD........etc, and can be filter by their tags, it is pretty like filterable post which can filter courses)

Point 2: Directory page is blank, did you added the shortcode? on that page to show the directory and the same page should be connected in appointment setting

>>>i have added the short code on the page:https://prnt.sc/tyea7c but still not working:https://prnt.sc/tyftw7 what do I missed? please check dear!

Point3: Yes, Loco Translate will be helpful here and create a separate topic

>>>Thank u dear, got it!
