500 Internal Server Error error

Hi,

I have a “500 Internal Server Error” everyday and I was wondering if you can help me with this issue.

So every time I get this issue, I just modify the file “.htaccess” which I think is the source of my problem 🙁

Here is how my htaccess looks like before I modify it:

# BEGIN iThemes Security
#Quick ban IP. Will be updated on next formal rules save.
SetEnvIF REMOTE_ADDR “^110\.85\.75\.214$” DenyAccess
SetEnvIF X-FORWARDED-FOR “^110\.85\.75\.214$” DenyAccess
SetEnvIF X-CLUSTER-CLIENT-IP “^110\.85\.75\.214$” DenyAccess
order allow,deny

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ – [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

# END WordPress
Cond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

# END WordPress

So every time I have this problem, I just edit this file and then the website works!

So eevryday, I modify my htaccess file with this code:

# BEGIN WordPress

<IfModule mod_rewrite.c>
ErrorDocument 404 /index.php?error=404
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

# END WordPress

I found this solution here : https://wordpress.org/support/topic/500-internal-server-error-on-all-wp-pages?replies=7

Do you know why my htaccess file is still automatically modified?

Thanks for your help!
