 * I’m having issues with my website. The CPU usage is too high and this is causing
   error messages. After contacting my webhoster they recommended to disable Wordfence
   because of this in the error log:
    – [Tue May 04 14:30:44.331210 2021] [lsapi:
   error] [pid 2594404:tid 140451084310272] [client 141.138.168.120:50780] [host

   LVE ID 1084), check [http://docs.cloudlinux.com/mod_lsapi_troubleshooting.html](http://docs.cloudlinux.com/mod_lsapi_troubleshooting.html),

 * Could Wordfence be the isssue for this problem? Is there a way to solve this 
   without disabling Wordfence?

 * Hello [@enna123](https://wordpress.org/support/users/enna123/) and thanks for
   reaching out to us!
 * Can you send a diagnostic report to **wftest @ wordfence . com**? You can find
   the link to do so at the top of the **Wordfence Tools > Diagnostics** page. Then
   click on **“Send Report by Email”**. Please add your forum username where indicated
   and _respond here after you have sent it._
 * Thanks again!

 * Thanks for sending that!
 * I don’t see anything jumping out from the diagnostic that would point to what
   is causing the CPU issue. Do you happen to have any PHP error logs I can look
   at? If so, could you send them to wftest @ wordfence .com with subject ” enna123
   for WFADAM “.
 * If you need help:
    It might be best if you could enable WordPress Debugging, 
   so we can see the exact errors your site is receiving. Debugging PHP code is 
   part of any project, but WordPress comes with specific debug systems designed
   to simplify the process as well as standardize code across the core, plugins 
   and themes. This page describes the various debugging tools in WordPress and 
   how to be more productive in your coding as well as increasing the overall quality
   and interoperativity of your code.
 * For non-programmers or general users, these options can be used to show detailed
   information about errors.
 * [https://wordpress.org/support/article/debugging-in-wordpress/](https://wordpress.org/support/article/debugging-in-wordpress/)
   can walk you through enabling the error logs on your site. Once you have this
   enabled, your site will generate error logs, which will help us figure out what
   might be causing your issue.
 * Thanks again!
