Problem 1: During Wordfence scan, it spits out this error in the logs from time to time: Wordfence DB error in /media/www/wp-content/plugins/wordfence/lib/wfLog.php line 474: BIGINT UNSIGNED value is out of range in '(('1341797005' + 86400) - unix_timestamp())'
How to reproduce: Do a Wordfence scan and check the logs during the scan
Frequency: A number of times every scan
Assumed fix: Change database column type?
Problem 2: Non-routine scanning
Sometimes Wordfence does not do a scan when it is supposed to... assuming it's a cronjob error. Cronjobs are enabled and being executed every 5 minutes.
How to reproduce: Check Wordfence every day for a period of time and eventually you'll notice it is no longer routinely scanning until you initiate a manual scan.
Problem 3: IP permanent blocks not being permanent
Permanently blocking an IP actually is not permanent... it's just like the time-limited block.
How to reproduce: Block an IP address from live traffic. Then go under Blocked IPs and click block permanently for that IP. Wait for the duration you have set for a time-limited block and the permanent ban is gone.
Severity: Major (because I can't permanently block IPs trying to hack the website
I appreciate your help ahead of time!
