Question

I am using wordpress latest version.

Currently my blog is set to custom permalink /index.php/%postname%/

http://abc.com/blog/index.php (working fine)

but when click on NEXT button to go to page 2, it fail.

It suppose to go to http://abc.com/blog/index.php/page/2/

But it go to http://abc.com/blog/index.php/Index.php/page/2/

(an extra /Index.php/ is being added….)

This happen only to page 2.
At page 2 go to page 3 onwards, the url is working properly.

Answer 1

It is very easy to fix.

Just put a line at
clean_url() function in wp-includes/formatting.php:

$url = str_replace('index.php/Index.php','index.php',$url);

just give this line at the beginning of the function before any “if Statements”
