**Your software**  
My Mautic version is: 4.4.5  
My PHP version is: 7.4.33  
My Database type and version is: 10.2.44-MariaDB-1:10.2.44+maria~bionic-log

**Your problem**  
My problem is:  
When I enter Mautic, the initial page loads for me to log in. Once I log in, it takes time to load and this error appears:

 ![image](https://us1.discourse-cdn.com/flex020/uploads/mautic/original/2X/f/f1b0cce1f348ca942a13b7a3af4965d384b1745b.png)

I refresh and after a minute, It loads.  
But sometimes I also have the Apache screen with the same warning…

What I’ve notice is that only with Administrator Users we have this issue.

These errors are showing in the log:

Hi, this is an nginx issue.  
Try to make sure your webserver knows where your Mautic folder is.
