Error     PHP

Apache PHP logfile:

[Sat Oct 29 02:58:38.90727 2016] [core:alert] [pid 13651] [client IP:59364 /var/www/cloud.domain.ltd/data/.htaccess: Expected </IfModule> before end of configuration

Integrity status for oC9+

No errors have been found.

It looks quite similar to this issue (The requested uri(\/login) cannot be processed by the script ‘\/owncloud\/index.php’) but I don't have the same log error.

EDIT: I tried # chmod o+rx cache. I don't get the php error which fails to open the directory. However, I still have the index error. My created users can not log in.

Can you post this file? There seems to be a syntax error (did you modify it?).

Besides the mentioned .htaccess also fix the permission issue on:

/var/www/cloud.domain.ltd/data/user/cache

My .htaccess was wrong so I put a new one from the owncloud website:

I don't have error anymore in the owncloud scan but my created users can not log in (only the admin can).

Sorry for my misleading post. It was not a solution. It is the content of my actual .htaccess in /var/www/cloud.domain.ltd/ directory.

So lets close this then as two of the three different issues in here (.htaccess and permissions) are solved. This avoids that people are posting the well known "i have the same problem" or "same here" posts and just starting a messy thread with that.

For your issue about the users not able to login please create a new thread. When doing so please:

  1. Explain exactly "but my created users can not log in" as this contains no information what happening if these users are trying to login
  2. Empty your data/owncloud.log to make sure that you don't have any log entries of your previous solved issues in there.
