First of all thank you for showing interest in our plugin.
The best way to identify what is causing the plugin not to work, can you please enable logging on WP Security Audit Log by following the below procedure and send us the debug log files?
1. Disable the plugin
2. Open the file wp-security-audit-log.php from the plugin directory (/wp-content/plugins/wp-security-audit-log/)
3. Uncomment line 51 and 52 by deleting the first forward slash characters of each line. Therefore line 51 and 52 should look as follows:
4. Enable the plugin and do an action that is typically logged, such as creating a new blog post and saving it as draft
5. Navigate to the plugin directory (/wp-content/plugins/wp-security-audit-log/)
6. Download the file debug.log, zip it up and send it to us via email to firstname.lastname@example.org.
Note: If there is also a file error.log please add it to the zip archive and send it to us.
The debug log file should contain enough information to help us determine what the problem is.
Thank you and looking forward to hearing from you.
Sorry for any inconvenience caused.
