Under the 'SEO & URL' section, trying to setup "Friently URL" for the domain - I see a message
URL rewriting (mod_rewrite) is not active on your server, or it is not possible to check your server configuration. If you want to use Friendly URLs, you must activate this mod.
I am using other domains [most of them using WordPress], so am sure that the mod_rewrite is enabled BUT somehow Prestashop [the only Prestashop install on this server]is not able to check it from the server.
Expected behavior
The settings on that page are used to recreate the .htaccess in the root folder, which is not being generated due to the problem as stated above.
Note: I just checked my cPanel log and found this
[15-Oct-2020 03:10:44 US/Eastern] PHP Warning: Use of undefined constant MCRYPT_RIJNDAEL_128 - assumed 'MCRYPT_RIJNDAEL_128' (this will throw an Error in a future version of PHP) in /home/nikpaul/public_html/nikshop/classes/Rijndael.php on line 124
in there, sharing it here as it may be pointing to something meaningful.
