try to add custom rule to htaccess = server error?

  • Hi,
    because of a problem in the rewrite rules that WordPress generates
    (nextpage feature results in 404 error because a rewrite rule is too
    greedy) I’ve tried to edit the htaccess file, by changing an existing
    rule and be adding a new one.
    Unfortunately, this results in a 500 internal server error and the
    only information a get in the server log is:
    File does not exist: /home/myserver/public_html/500.shtml

    I’ve posted the full (unmodified) htaccess below, but the following
    is the rule in question:
    RewriteRule ^(.+)/([^/]+)(/[0-9]+)?/?$ /digitalcamera/index.php?category_name=$1&name=$2&page=$3 [QSA,L]

    As I said, this rule does not work as it should and will not put any
    page number in $3, because the first .+ is too greedy.
    I tried to solve this by changing this rule and adding another rule
    just below the existing rule:
    RewriteRule ^(.+)/([^/]+)/([0-9]+)/?$ /digitalcamera/index.php?category_name=$1&name=$2&page=$3 [QSA,L]
    RewriteRule ^(.+)/([^/]+)/?$ /digitalcamera/index.php?category_name=$1&name=$2&page=$3 [QSA,L]

    I’ve tested the rules seperately (outside of wordpress in a regex
    editor) and they seem to work, however as soon as I upload the modifided
    htaccess I get the 500 internal server error.

    Does anyone know how to successfully modfiy the htaccess without generating
    an error?

    Thanks.

    Steve

  • It may be because in your second rule, there is no 3rd regex match (i.e. something in the $3 variable).

    So, this:
    RewriteRule ^(.+)/([^/]+)/?$ /digitalcamera/index.php?category_name=$1&name=$2&page=$3 [QSA,L]

    should be this:

    RewriteRule ^(.+)/([^/]+)/?$ /digitalcamera/index.php?category_name=$1&name=$2 [QSA,L]

    Just a guess.

    Thanks for the reply VaamYob, I tried it but it doesn’t make a
    difference unfortunately.

    I don’t understand why adding an additional rewrite rule would cause
    an error 500.

    Steve

    Do you have access to the server logs ?

    The only access I have is an error log through my cpanel. As I said
    above the only error message I get is:
    File does not exist: /home/myserver/public_html/500.shtml

    Steve

    The server is looking for a 500.shtml because it’s been told to show that file whenever a 500 error occurs.

    Can you contact your host and ask them for a copy of your logs ?
