Resolution

Workaround

1. Log in to Plesk.

2. Apply one of the following steps to remove the duplicate directive:

   • Reset the max_execution_time value to default at Domains > example.com > PHP Settings and specify proxy_read_timeout in the Additional nginx directives field at Domains > example.com > Apache & nginx settings

   • Remove the proxy_read_timeout (if defined) from the Additional nginx directives field at Domains > example.com > Apache & nginx Settings and adjust max_execution_time in domain's PHP Settings.

     Note: If there are a lot of domains with both directives customized, see the command-line instructions below.

3. Go to Tools & Settings > Webserver Configurations Troubleshooter

4. Click the button > Set the Status filter to Error from the drop-down menu.

   

5. The list of broken configuration files will appear. Select all and click Rebuild > Selected.
