 * Hello together,
 * I installed Wordfence yesterday on my site. After the installation everything
   works well. But today I visited the site again and got an error. After activating
   the debug mode I found this:
 *     ```wp-block-code
       Warning: require_once(/data/web/1/000/137/653/526328/htdocs/wp-content/plugins/wordfence/lib/wordfenceClass.php): Failed to open stream: No such file or directory in /data/web/1/000/137/653/526328/htdocs/wp-content/plugins/wordfence/wordfence.php on line 125

 * I searched for this exact problem, but didn’t find another solution… Then I deactivated
   the wordfence-plugin per FTP and I was able to visit the frontend again. It was
   also possible to log into the admin dashboard, but I couldn’t open any function
   in the menu, cause of a 403 “You don’t have permission to access this resource”.
 * WordPress and all plugins are up to date. I work on a hosted apache server.
 * Does anybody has an idea about 1. the wordfence problem and 2. why I can’t enter
   any admin-functions?
 * I really hope for your help!

 * Hi [@romanofw](https://wordpress.org/support/users/romanofw/), Thank you for 
   reaching out.
 * Could you please provide more details on the second problem “**why I can’t enter
   any admin-functions? **“?
 * Additionally, please 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._
 * **NOTE:** It should look as follows – Screenshot of [Tools > Diagnostic > Send by Email](https://www.wordfence.com/wp-content/uploads/2021/09/diagnosticsendbyemail.png)
