Hello @haidermaa and thanks for contacting us!
When did this start happening? Was it after any updates to any specific plugins or themes?
I am wondering if there is a possible database issue with the plugin or a conflict that is preventing the page from loading. We could try one of two things here to see if we can resolve it.
To test a plugin/theme conflict:
You can disable your other plugins on the site one at a time and test, or alternatively, use the Health Check & Troubleshooting plugin (https://www.ads-software.com/plugins/health-check/). That is a plugin you will need to install from the Plugins > Add New area.
If you use the Health Check & Troubleshooting plugin, you can troubleshoot the site with just Wordfence enabled and the changes are only seen in the back end and not to visitors.
After downloading that, in the plugins section under Health Check & Troubleshooting you’ll see “Troubleshoot”. Click that and you’ll be in Troubleshooting Mode, which you will see a Troubleshooting Mode button in the top admin bar, which lets you know you are actively troubleshooting. (Note about that: Clicking Disable Troubleshooting mode in that area will turn off troubleshooting when you’re done testing for the conflict at the end.)
With Troubleshooting mode active, in the plugins section, you will see Enable while troubleshooting under all your plugins. Click Enable while troubleshooting under Wordfence, and your site on the backend will act as only Wordfence is enabled. Keep in mind, this doesn’t always rule out plugin conflicts, however, it can a good portion of the time.
Once you enable the troubleshooting with Wordfence, go over to the Wordfence plugin and check to see if the issues continue.
If this doesn’t seem to provide any insight into the issue, we could try a reset on Wordfence.
https://www.wordfence.com/help/advanced/remove-or-reset/#remove-or-reset can walk you through on doing that.
Let me know if any of this helps!
Thanks!
