I've made a slight mistake in my .htaccess and now i cannot access my page anymore

Question

To be more specific, i changed my php_value memory_limit accidently to 20GB while i was changing the maximum upload and post sizes. I changed it back to what it was 512MB but my page is still giving me a HTTP ERROR 500.

Anyone got any ideas what i'm missing?

This is my .htaccess

<IfModule mod_headers.c>
  <IfModule mod_setenvif.c>
    <IfModule mod_fcgid.c>
       SetEnvIfNoCase ^Authorization$ "(.+)" XAUTHORIZATION=$1
       RequestHeader set XAuthorization %{XAUTHORIZATION}e env=XAUTHORIZATION
    </IfModule>
    <IfModule mod_proxy_fcgi.c>
       SetEnvIfNoCase Authorization "(.+)" HTTP_AUTHORIZATION=$1
    </IfModule>
  </IfModule>

  <IfModule mod_env.c>

    SetEnv modHeadersAvailable true
  </IfModule>

This is my error log

Any help would be appreciated to the max

Answer 1

Your htaccess file is invalid. You are starting the directive <IfModule mod_rewrite.c> but never closing it using </IfModule>.

I would advice to download the default htaccess file shipped by nextcloud and try again. Just download the zip file from here: https://nextcloud.com/install/#instructions-server and replace the htacess file.

Answer 2

The htaccess settings are only used for PHP executed within that folder or sub folders - What is the difference between php.ini and .htaccess?

Looking at the error message (Allowed memory size of 2097152 bytes exhausted) suggests that composer has a much lower memory limit than what you set so my guess would be that it is not affected by your htaccess.

Try setting the limit in your php.ini file instead.
