The APS Catalog has been deprecated and removed from all Plesk Obsidian versions. Applications already installed from the APS Catalog will continue working. However, Plesk will no longer provide support for APS applications.
Please be aware: with the Plesk Obsidian 18.0.78 release, the support for the ngx_pagespeed.so module will be deprecated and removed from the sw-nginx package.
First of all you need to make sure that modules are installed on the server. Can you see them in Sitebuilder administrator CP -> Server -> Modules section? If you see there all modules it means that not all of them are included into plan. Each user is assigned to plan which have some properties as number of templates, modules ..etc. included. Try to check Users -> Plans -> PLAN_NAME -> Modules section. Select all necessary modules and add them to plan. After that modules should be available for you in Wizard.
Let me know if you need further assistance here.
In this case you better contact with Hostgator. By default all modules should be installed together with main Sitebuilder packages. Did you check Server -> Modules section in Sitebuilder admin interface? If all modules are listed there, then it should be installed.
