RESOLVED!
Modified the index.php from
require (‘./subdirectory/wp-blog-header.php’);*/
TO:
require( dirname( __FILE__ ) . ‘/subdirectory/wp-blog-header.php’ );
Hi t-p, thanks
I already checked out that codex guide but is not my case. It could not be related to the mod_rewite because I have didn’t changed the hosting server and before update everything worked well with Pretty Permalinks. The site is up and running since a lot of year, always with pretty permalinks…
Any idea??
