I setup nextcloud on namecheap hosting with cpanel. I have SSH enabled, SSL working, etc.
Installed by uploading setup-nextcloud.php and running that from my domain.
MySQL was easy to setup. PHP seems to be setup correctly too.
The install goes fine and nextcloud boots up. I can add apps, users, etc. But I have a few things that just do not work.
Issues:
Files and Images do not load
Nextcloud office does not load
Search function does not work and has error (But finds apps)
I reinstalled and reconfigured things differently maybe 6 times and this issue keeps happening.
Each reinstall I tried looking into different things such as: the .htaccess file, php plugins, file and folder permissions, changing data folder location, and many other things.
Please use browser developer tool (in Mozilla Firefox F12) and there Network Analysis. Reload and post errors. Do yo use a filter software, adblocker, …? Can you test with another browser and another computer? Hopefully it is a client problem (e.g. Javascript).
I would focus on NS_BINDING_ABORTED for /remote.php/dav/ URI. From you screenshot it looks like the browser tries to load the resource with plain http (missing lock icon) which fails might be blocked for different reasons.
Please review if you system has correct overwrite* settings in the config.php
