PHP configuration option output_buffering must be disabled

[jdaviescoates]

Searching the Nextcloud Docs I found this:

Output Buffering must be turned off in .htaccess or .user.ini or php.ini, or PHP will return memory-related errors:
output_buffering = 0

On this page https://docs.nextcloud.com/server/25/admin_manual/configuration_files/big_file_upload_configuration.html

Not sure how/ where best to achieve this on Cloudron? (and I'd expect the package to do it for me, really )

Additionally, I clicked on the log shown in the screenshot above and it took my to /settings/admin/logging

But it doesn't load. Just have a spinning wheel spinning.

Hmz, I'm not getting this on another install of Nextcloud running the exact same version on the exact same Cloudron...but with less plugins, so I guess it may be one of the plugins that is causing it.

Still would be nice to get it sorted

this one is a nextcloud bug. If you log to stdout/stderr instead of a file, that UI breaks.

Got a link to an existing issue we can chime in on?

I've no idea what that means, but OK

Can you check if your /app/data/htaccess has https://github.com/nextcloud/server/blob/master/.htaccess#L71 ?

(Note, this file is different from /app/data/.htaccess)

<IfModule mod_php.c>
  php_value mbstring.func_overload 0
  php_value default_charset 'UTF-8'
  php_value output_buffering 0
  <IfModule mod_env.c>
    SetEnv htaccessWorking true
  </IfModule>
</IfModule>

@girish said in PHP configuration option output_buffering must be disabled:

php_value output_buffering 0

It does have that, but within this:

<IfModule mod_php7.c>
  php_value mbstring.func_overload 0
  php_value default_charset 'UTF-8'
  php_value output_buffering 0
  <IfModule mod_env.c>
    SetEnv htaccessWorking true
  </IfModule>

Can't help notice that php7 in there, perhaps that's the issue.

[jdaviescoates]

Aha, and in my other Nextcloud that isn't having this issue there is this:

# PHP 7.x
<IfModule mod_php7.c>
  php_value mbstring.func_overload 0
  php_value default_charset 'UTF-8'
  php_value output_buffering 0
  <IfModule mod_env.c>
    SetEnv htaccessWorking true
  </IfModule>
</IfModule>

# PHP 8+
<IfModule mod_php.c>
  php_value mbstring.func_overload 0
  php_value default_charset 'UTF-8'
  php_value output_buffering 0
  <IfModule mod_env.c>
    SetEnv htaccessWorking true
  </IfModule>
</IfModule>

[jdaviescoates]

So, I guess I could try just copy pasting this bit:

# PHP 8+
<IfModule mod_php.c>
  php_value mbstring.func_overload 0
  php_value default_charset 'UTF-8'
  php_value output_buffering 0
  <IfModule mod_env.c>
    SetEnv htaccessWorking true
  </IfModule>
</IfModule>

Into the /app/data/htaccess file on the Nextcloud where I'm hitting this issue.

I guess that would very likely make it work...

But also wondering if I should perhaps just copy/ paste the whole file. Or perhaps the app package could include the above in an update?

[girish]

@jdaviescoates yes, just copy/paste the whole file. Ideally, nextcloud should be "upgrading" this file but it isn't. Let me see why it's not.

I have fixed the code now to always copy over the latest htaccess.
