Problem with base_url() and files not loading

[eluser]TheFuzzy0ne[/eluser]
First of all, this line is unnecessary:

Code:

RewriteCond $1 !^(index\.php|images|assets|css|js|robots\.txt)

The two lines below it ensure that the rewrite rule only fires if the directory/file exists. I think that this may be the line that's causing the problem, as all requests will always be passed to index.php, because the request URI never starts with index.php, images, assets, css, js or robots.txt - They always start with "/beta".

Good luck!
