I have the most recent wordfence plugin (updated today) and the previous version before it.
Although i have had continued problems with the plugin - it kicks me out and basically it locks down my site into a datebase server error.
I have been dealing with my host for the last 5 weeks or so over this and they have emailed again today to confirm that the gist is:
Effectively, the plugin locks files and causes issues with access to the site.
Which is driving me to distraction and wondered if anyone knew how to rectify as surely i am not the only one getting this .. am i?
