 * Hi, I recently found I was getting critical errors when I published listings 
   on my site. I asked my theme’s author for help and he asked for WPAdmin and FTP
   access I set ac/n account up for him but then found all admin accounts were listed
   as inactive. I turned off wordfence and everything worked again. I would like
   to use wordfence but need this fixed in order to use it. Can anyone help please?
   
   Thanks Andrew

 * Hi [@hampalm1](https://wordpress.org/support/users/hampalm1/), thanks for getting
   in touch.
 * Do you have any examples of the critical error messages, as these could help 
   me identify the scripts or plugin that might be causing them, and critically 
   whether they are directly linked to Wordfence. I wouldn’t rule out a Javascript/
   plugin conflict at this stage, you can show us errors here to assist with a service
   like [Snipboard](https://snipboard.io/).
 * In the mean time, you could also try disabling all plugins _except_ for Wordfence
   and reverting to a default theme such as Twenty Twenty-One. Does the behaviour
   continue when Wordfence is the only plugin enabled? If not, re-enable your plugins
   one-by-one and finally your theme to see when it starts reoccurring. You can 
   install a maintenance mode plugin during this time if site visitors are likely
   to be affected. Browser extensions can also sometimes interfere with these pages
   so disabling those at the same time, or using a different browser to your default
   may be an idea during this period of testing too!
 * Let me know how you get on!
 * Peter.

    Does this help: [https://www.loom.com/share/43113fd88e094d2580b43dd0cf5514a0](https://www.loom.com/share/43113fd88e094d2580b43dd0cf5514a0)?
 * I did try turning all plugins off except wordfence and still got the errors it
   was only without wordfence on it would work and that was with the other plugins
   on.
 * Kind regards

 * Hi [@hampalm1](https://wordpress.org/support/users/hampalm1/), thanks for your
   very detailed video.
 * The key error for me is the E_ERROR mentioned at the bottom of the email caused
   by your theme. It states that an object cannot be converted to a string so something
   is being passed in the background as a variable of the wrong data type. You may
   need to contact your theme developers to see if a recent theme update may have
   either broken, or if you haven’t updated and there are updates available, fix
   this issue.
 * You could try running Wordfence in [Learning Mode](https://www.wordfence.com/help/firewall/learning-mode/)
   just in case there is a block happening in the background that is causing the
   object/string issue that causes the theme to fail, although I cannot guarantee
   this will help.
 * 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 that were causing issues as shown in your video.
   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.
 * Thanks again,
 * Peter.
