As per the link offered earlier in this thread: http://codex.wordpress.org/Using_Permalinks#Creating_and_editing_.28.htacces
“Where’s my .htaccess file?
Wordpress’s index.php and .htaccess files should be together in the directory indicated by the Blog address (URI) setting on your General Options page”
To find your “General Options” page you go into your wordpress admin page click on “Settings” then “General“. There you will find two options “WordPress address” and “Site address“. I am assuming both have http://millinersboutique.com listed, which means your posts should show as:
http://millinersboutique.com/postname
and NOT something like this:
http://millinersboutique.com/wordpressorsomething/postname
(On my site, I use the latter format and have two htaccess to mess up lol)
The .htaccess file will be not be recognizable so that is fine (as you saw you can still open it/edit it in Notepad.) My basic understanding of htaccess is it basically tells the browser how to get to your posts. As per that link again, it looks like your htaccess file is missing one important code block that tells the browser how to find your wordpress posts and that is:
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress
When I had issues, one reason was because this was missing. The other was because a plugin had written other stuff on it. It is okay for plugins to write stuff on your htaccess file, but sometimes it breaks it.
I can see from what you have posted that you have at least two plugins that influence the htaccess file: AnyFont and FrontPage. So from here you can try two things: add the missing code and see if it works, or deactivate those those plugins first then see if it works.
Most people would suggest to deactivate those plugins and then go from there, however, even if it works after you deactivate them, once you reactivate them again, you may come across the same problems – and I assume you want to see it you can keep those plugins, right?
What I would try:
1. Keep the .htaccess file downloaded ‘as is’ (in case you want to come back to this state) – possibly save it in a folder called ‘old‘ to not confuse with any new htaccess you have to work with.
2. Open that .htaccess file and the code I pasted above to the beginning of the htaccess file (ie before “# BEGIN AnyFont“)and resave the file as .htaccess in a different location on your PC than the original (another folder names “new” for example.)
Notepad will try to put a .txt extension on it, so try to prevent that by changing “save as type” from “Text Documents (txt)” to “All Files (*.*)” so if you can save it without that extension. However this doesn’t always work and you may still find it saved on your PC as “htaccess.txt“. If so, open it again and resave save it without the txt on the end (with “All files (*.*)” selected. I have found that the second try works.
3. Upload this new .htaccess file to the same spot on your website where you found the original. It will warn you that you are replacing the original, which is what you want to do.
Check your site (you may have to clear your internet cache). If everything works, great! But if not, you many have to get rid of those plugins.
I think we are on the right track.. just now I did a search for “index/php htaccess” and came up with this thread with a similar issue to yours (except they have no plugins and are using a subdirectory):
