Problems in options-reading.php

I have find out that if you go to Options->Reading and you try to do any changes to it there is an error message stating showing the following:

Forbidden
You don’t have permission to access /wp-admin/options.php on this server.

This error message somehow goes away if you modify the original options-reading.php file from the original line:

<input type=”hidden” name=”page_options” value=”posts_per_page,posts_per_rss,rss_use_excerpt,
blog_charset,gzipcompression,show_on_front,page_on_front,
page_for_posts” />

To this updated one:

<input type=”hidden” name=”page_options” value=”show_on_front,page_on_front,page_for_posts,
posts_per_page,posts_per_rss,rss_use_excerpt,blog_charset” />

Basically, what you do is remove the gzipcompression, from the original line, this allows the Options->Reading to work, nevertheless, the same error message comes back after you have updated the Reading settings and are back to the parameters page with the following URL:
wp-admin/options-reading.php?updated=true

In order to change the settings again you must go to a different section of the Options page and clic on the Reading section again.

I hope this helps.
