    Try this, WHM>>>mod security>>>edit config and add/check for the following:
    SecPcreMatchLimit 100000
    SecPcreMatchLimitRecursion 100000

    If you are still getting the same issues try to add following value on your server

    Php.ini file
    Code:
    pcre.backtrack_limit = 10000000
pcre.recursion_limit = 10000000
    modsec2.user.conf file
    Code:
    SecPcreMatchLimit 150000
SecPcreMatchLimitRecursion 150000
     
    Stop hovering to collapse... Click to collapse... Hover to expand... Click to expand...

    Hello,

    Thank you, i have added the changes within PHP.INI and modsec2.user.conf. and placed the both within them.

    one question, Atomic rule are auto updated ? or i need to update them ? if yes so How ? and once they updated or php upgraded should i need to place this changes again ?


    Thanks

    Hello :)

    It's important to keep in mind that these are custom Mod_Security rules provided by Atomicorp. An error or warning message related to these rules is more likely the result of a problem with the custom rules, as opposed to an issue with EasyApache or Mod_Security itself. You can find support for their custom rules at their website:

    Atomicorp/GotRoot Realtime Modsecurity Rules Support

    Thank you.
