Do you see any error or warning in the log? * You can also enable WordPress debuggingand see if there’s anything written to the PHP error log: 1. Edit your wp-config.php 2. Search for: `define('WP_DEBUG', false);` 3. Replace with: `define('WP_DEBUG', true);` 4. Add this line below:` define( 'WP_DEBUG_LOG', true );` * The log (if any) will be located in “/wp-content/debug.log”. * Thread Starter [bilip](https://wordpress.org/support/users/bilip/) * (@bilip) * [5 years, 1 month ago](https://wordpress.org/support/topic/checking-wordpress-files-integrity/#post-14018397) * That´s the text from the Log-Tab: * 07-Feb-21 11:07:15 INFO Processing step 1/14 07-Feb-21 11:07:15 INFO Checking NinjaScanner files integrity 07-Feb-21 11:07:15 DEBUG Using local cached version of checksums 07-Feb-21 11:07:16 INFO Files integrity is O.K 07-Feb-21 11:07:16 DEBUG Process executed in 0.8 seconds and used 68,42 MB of memory (NinjaScanner additional memory: 0,00 MB). 07-Feb-21 11:07:17 INFO Processing step 2/14 07- Feb-21 11:07:17 INFO Building file’s list 07-Feb-21 11:07:24 INFO Total files found: 12.071 07-Feb-21 11:07:24 INFO Building database posts and pages checksum 07-Feb-21 11:07:24 INFO Found 0 posts and 17 pages in the database 07-Feb-21 11:07:26 DEBUG Process executed in 9.72 seconds and used 68,42 MB of memory ( NinjaScanner additional memory: 0,00 MB). 07-Feb-21 11:07:29 INFO Processing step 3/14 07-Feb-21 11:07:29 INFO Checking WordPress core files integrity 07- Feb-21 11:07:29 DEBUG Using local cached copy (wordpress-5.6.1-de_DE.zip) 07- Feb-21 11:07:29 DEBUG Building files list from ZIP archive 08-Feb-21 00:00:06 ERROR Security nonces do not match. 08-Feb-21 00:00:07 ERROR Security nonces do not match. * Plugin Author [nintechnet](https://wordpress.org/support/users/nintechnet/) * (@nintechnet) * [5 years, 1 month ago](https://wordpress.org/support/topic/checking-wordpress-files-integrity/#post-14020618) * Unfortunately, there’s nothing in the log.

You coud also have a log in your WP root folder (error.log or error_log). * Do you have another security plugin that is doing rate-limiting?

Did you check the HTTP server log for HTTP POST requests to the “admin-ajax.php” script such as this one: `"POST /wp-admin/admin- ajax.php HTTP/2.0" 200` Do they all return a “200” HTTP code? * Alternatively, can you change the forking method: NinjaScanner > Settings > Advanced Users Settings > Scanning process” and select “Fork process using WordPress built- in WP-CRON”. The scanner will rely on /wp-cron.php instead of /wp-admin/admin- ajax.php. * If the scan hangs after 5mn, you can click the “cancel” button, no need to wait for hours. - This reply was modified 5 years, 1 month ago by [nintechnet](https://wordpress.org/support/users/nintechnet/). * Thread Starter [bilip](https://wordpress.org/support/users/bilip/) * (@bilip) * [5 years, 1 month ago](https://wordpress.org/support/topic/checking-wordpress-files-integrity/#post-14045172) * 1st: If i select /wp-admin/admin-ajax.php in Browser, then i have 0 as return * 2nd: For WP-Cron i get * Fatal error: the HTTP server returns a [500 Internal Server Error] HTTP code.

The scanner forks a process which then will connect back to the site and you won’t be able to see that from the console, only in the HTTP logs. All requests should return a “200” code. * Regarding WP-Cron, you’ll need also to check the log. It too should return “200”, not “500”. I’m still thinking there’s an issue (or a restriction) with your server that blocks the requests. Did you check your .htaccess too? Are there any rules that could block or mess with AJAX and WP-CRON? * Thread Starter [bilip](https://wordpress.org/support/users/bilip/) * (@bilip) * [5 years, 1 month ago](https://wordpress.org/support/topic/checking-wordpress-files-integrity/#post-14069467) * May you help me remote?

But if you can get the logs as mentioned in my previous message that would help us. How about your .htaccess too? Did you check it? Also, is this your own server or a shared hosting account?
