    I am on a shared server bc I have a small, mostly text site, with very low traffic. I’ve been getting 5xx server errors upon crawls. Error logs are showing that WordFence was causing some of them. Wondering how to fix this? I have disabled it for now. Below is the email from my hosting service including the log errors (dreamhost is my host):

    “I checked the error logs for the domain around the time stamp of when we
    received your last reply and saw the following errors repeatedly logged :

    This indicates the plugin name ‘wordfence’ is causing errors to occur.
    You may want to try temporarily disable the ‘wordfence’ plugin

  • Hi @gatehealing,

    We’ve had users have a similar issue in the past, and what seems to work is by adding a configuration to php.ini.

    Edit php.ini and add the following line:

    pcre.jit = 0

    This will disable just in time for the regex module, and you should no longer see those errors.
