My Joomla is wrong on the local site
I have a site that I’ve downloaded for someone and I’ve installed it in local. I do not know what JoomlLeauer is and what’s wrong with me!
( ! ) Deprecated: iconv_set_encoding(): Use of iconv.internal_encoding is deprecated in F:\wamp64\www\ طراحیسایت\public_html\libraries\joomla\string\string.php on line 27
( ! ) Warning: session_start(): Cannot send session cookie - headers already sent by (output started at F:\wamp64\www\ ثبتدامنه\public_html\libraries\joomla\string\string.php:27) in F:\wamp64\www\hadidsaz\public_html\libraries\joomla\session\session.php on line 658
Thank you for advising me on how to fix this error
