ownCloud can flag a faulty code integrity check for several reasons--moves to a new server, modified core files, or custom patches. Use the configuration toggle below to silence the warning safely.
Modify ownCloud config.php
The file is usually located at /PathToYourOwncloud/config/config.php. Open
it with
your preferred editor.
nano /PathToYourOwncloud/config/config.php
Add the following line before the closing parenthesis: 'integrity.check.disabled'
=> true,
Then your configuration should look similar to:
<?php
$CONFIG = array (
'instanceid' => 'rcdyskettch4',
'passwordsalt' => 'lrItsujIuShjLjkhnjkPjkekjtrNtr8trzcFDGj',
'secret' => 'y+1GmdcgfgdoremasöLMmkbjkbKBjjknnja/Ci',
'trusted_domains' =>
array (
0 => 'owncloud.saas-secure.com',
),
'datadirectory' => '/PathToYourOwncloud/owncloud.saas-secure.com/data',
'overwrite.cli.url' => 'https://owncloud.saas-secure.com',
'dbtype' => 'mysql',
'version' => '9.0.2.2',
'dbname' => 'owncloud',
'dbhost' => 'localhost',
'dbtableprefix' => 'oc_',
'dbuser' => 'owncloud',
'dbpassword' => 'owncloud',
'logtimezone' => 'UTC',
'installed' => true,
'loglevel' => 4,
'mail_from_address' => 'owncloud',
'mail_smtpmode' => 'php',
'mail_domain' => 'saas-secure.com',
'memcache.local' => '\\OC\\Memcache\\APCu',
'integrity.check.disabled' => true,
);
Log in as an admin and, if the message "There are problems with the code integrity check. More information ..." still appears, open the Admin page and click Rescan.
After rescanning, the warning should disappear and stay away.
