Logs deleted after update?

Hi,

They are deleted by WP (it flushes the whole plugin directory before installing the update). But NF will save a copy to the DB and restore it afterwards.
Did you update it manually or was it updated automatically by WP ?

That’s weird. Normally it will compress and backup the log to the DB in a ‘nfw_tmp’ temp row inside the ‘wp_options’ table, then will restore the log and the stat file right after the update:
-ninjafirewall/log/firewall_YYMM.php
-ninjafirewall/log/stats_YYMM.php

Then, it will delete the ‘nfw_tmp’ row.

We have about 2 dozens of sites running it for testing purpose and I just checked and saw that all of them had their log restored.

Do you see any ‘nfw_tmp’ row left in your ‘wp_options’ table?

I think I misunderstood your issue: the current month log was saved (2014-08) but the previous month(s) log(s) were deleted, it that what you mean?

Only the current month log is saved because WP deletes all files and it is a pain to manage. We are thinking of the way to preserve all logs. Most security plugins log to database but that is crazy and awfully slow.
Probably we’ll use a directory outside the plugin folder but it has to be safe and protected.
That’s on our to-do list.

Adding a download link would be a good idea, I put this on the to-do list!

I am not sure about sending logs by email tough, because some very busy sites/multi-site have huge logs (dozens of MBs).

You can use the helpdesk for that purpose.
