Buonasera, spero che qualcuno qua mi potrebbe aiutare con questo problema..

Ho problemi con il .htaccess rewrite, per impostarlo bene, aiutatemi per favore!

Il atuale codice:

RewriteEngine OnRewriteBase /
RewriteCond % ^ ww* . letsplanmywedding . com
RewriteRule ^(.)$ htt : // letsplanmywedding . com/$1 [L,R=301]

RewriteRule ^category-([A-Za-z0-9_&]+).html$ productpage.php?productid=$1

Cercando con vari tools ho visto che il ww* non si reindirizza al sito senza ww*, il principale indirizzio deve essere senza ww* .

Inoltre ho trovato che -

4 pages returned a 200 response. This indicates potential for duplicate content problems. Ideally, only htt* :// ww* . letsplanmywedding . com **OR *htt:// letsplanmywedding . com should return a 200 response.

Dove posso trovare uno script o qualcosa per inserire una chat nel proprio sito però che non abbia la pubblicità e da chi è fatta:bho:

chi mi aiuta a risolvere questi errori?:(
Notice: Undefined index: username in y:\home\login\www\index.php on line **88
