I noticed on some server setups I could not do the following inside a .htacess file:
<br> php_value upload_max_filesize 250M<br> php_value post_max_size 250M<br>
I was getting an error 500 Internal Server Error with the above code in the .htaccess file.
What to do to correct this is create a file called php.ini and save it in the same location as your .htaccess file and enter the following code instead:
<br> upload_max_filesize = "250M"<br> post_max_size = "250M"<br>
