I have an on-premises installation of SharePoint 2013 on a development server, with a dedicated SQL Server instance on another server. Recently, my Central Administration site would stop loading and show a simple white screen.
Looking at the page source that comes back, I get the following:
<html><head><META HTTP-EQUIV="Content-Type" CONTENT="text/html; charset=utf-8"><meta name="Robots" content="NOINDEX " /></head><body></body>
<script type="text/javascript">
var gearPage = document.getElementById('GearPage');
if(null != gearPage)
{
gearPage.parentNode.removeChild(gearPage);
document.title = "Error";
}
</script>
</html>
I do not see any errors in the ULS or in the server event logs.
I have restarted both IIS and the SharePoint server. I have also successfully re-provisioned the Central Administration instance by using the following commands:
Unprovision: psconfig.exe -cmd adminvs unprovision
Provision: New-SPCentralAdministration -Port <your-port-num>
This post suggests that SharePoint be completely re-installed, but that's not an acceptable solution for me. Does anyone have any suggestions for this issue?
