[resolved] PHP error, non-routine scanning, IP blocks gone (2 posts)

    WordPress version: 3.4.1
    Plugin version: Most recent one as of July 10, 2012, 1231pm EDT

    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
    Priority: Low
    Severity: Minor
    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.
    Frequency: Random
    Priority: High
    Severity: Minor

    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.
    Frequency: Always
    Priority: High
    Severity: Major (because I can't permanently block IPs trying to hack the website

    I appreciate your help ahead of time!

    Thanks for the professional bug reports. This format and your effort is very very much appreciated.

    I've logged this in our bug tracker as priority 1 and we'll get to it ASAP.

    Initial feedback:

    Problem 1: Looks like MySQL doesn't like to compare a negative value against a bigint column so we're going to change the compared value rather than the column type.

    Problem 2: We occasionally decrease scanning frequency to reduce load on our servers. We will soon introduce a paid feature that lets you control this instead.

    Problem 3: We're aware of this but have had trouble reproducing it and I think your repro will help us get this fixed fast.

    Thanks again!!

    Mark Maunder.
