 * Hi, I am facing a critical error on my website while using Wordfence. When I 
   am deactivating it then the website is working fine. Please give me a mail id
   in which I can share a screenshot of it.
 * Also facing 500 Error on Customization

 * Hi [@baglagroup2019](https://wordpress.org/support/users/baglagroup2019/), thanks
   for reaching out to us.
 * You can use a free service such as [Snipboard](https://snipboard.io/) to drop
   screenshots here for us to review what you’re seeing.
 * If you are able to still reach the admin area of your site when Wordfence is 
   active, it’d be really helpful to send over your diagnostics. Can you send them
   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._
 * _**Note:** For the fastest response time, please make sure and add any information
   or questions directly to this topic and not the email address above unless asked._
 * If that’s not possible, we can try troubleshooting from the information we have.
 * Thanks,
 * Peter.

 * Hi [@baglagroup2019](https://wordpress.org/support/users/baglagroup2019/), thanks
   for getting the screenshot and diagnostic to us.
 * I have been on annual leave and have been catching up on responses that may have
   been missed in the mean time as WordPress forums don’t return all new topics 
   to the top for attention.
 * I was initially under the impression you were receiving a full server 500 error
   which would not show any of the site, which would involve looking at the error
   logs. However, as the front-end still loads but something such as a script or
   plugin is being stopped, I suspect this is a case for [Learning Mode](https://www.wordfence.com/help/firewall/learning-mode/)!
 * From the Wordfence Dashboard click on Manage WAF. Then you will see **Basic Firewall
   Options > Web Application Firewall Status**. Change the option to **Learning 
   Mode**. Now perform the actions such as page loads or edits that were causing
   issues. This will help Wordfence learn that these actions are normal and it will
   allow them in the future. After you have finished performing the actions, switch
   the WAF from Learning Mode back to **Enabled and Protecting**. Now test to see
   if these actions work correctly.
 * Let me know how you get on!
 * Thanks again,
 * Peter.

 * I have done all the processes but the issue is the same.
 * I recently found in one of my another website I am facing the same 500 error 
   in it. I just shared the diagnostic report with the same username.
