I was getting the anoying Error 500 - Internal server error on my 1and1 home shared hosting again.

I tried all the fixes on this site but still not getting passed the error page.

Then I realized that the front page of my site was working fine but the resto of the pages weren't. So I figured that there might be a problem with the clean URLs. I checked my .htaccess file and there it was.

# RewriteBase /

I uncommented that line.

RewriteBase /

This solved the problem.

 

I am developing drupal sites locally on my MacBook using MAMP.

I was getting a lot of memory limit errors.

I modified the php.ini file and also the settings.php fiel in drupal. None of them solved my problems.

I inserted this line in my .htaccess file inside the drupal folder:

php_value memory_limit  "100M"

That line goes right after

# PHP 5, Apache 1 and 2.
<IfModule mod_php5.c>

This solved my problem.

 

Copy and paste the following line at the beginning of your .htaccess file:

##
AddType x-mapp-php5 .php
AddHandler x-mapp-php5 .php
##

go to http://drupal.org/node/232773 for the complete drupal forum post.

ADDITIONAL IMPORTANT INFORMATION

.htaccess code snippet to have any url to redirect to another url. You would insert this in your .htaccess file. This is very useful when you are migrating a static html site into a Drupal site.
