hi
welcome joomla , these forums.

remember in your best interest take backup of site:

• before running update release of joomla
• before updating existing extensions
• before installing new extensions.
• before deleting extension (particular core extensions)
• before moving subfolder/ root/
• before moving localhost/ remote host
• before making changes access control levels.
• before editing core files of joomla reason
  • note:this not recommended anyway! except on rare occasion when official, approved patch released prior full update being available joomla developers.
• on regular basis site protect new content added:
  frequency regular backups varies depending on site, it's traffic, , changes content:
  
  • it may every hour
  • it may 2/3 times day or more
  • it may once day
  • it may once week
  • it may once month
• essentially, any time if there chance things go wrong, have backup fall to!

if have changed seo or ssl settings in joomla configuration edit configuration.php file , reset these default settings,

code: select all

   public $sef = '1';
   public $sef_rewrite = '0';
   public $sef_suffix = '0';

code: select all

   public $force_ssl = '0';


and rename .htaccess file (if created) htaccess.txt.
