SharePoint Quick Launch not opening - sharepoint

Question

I want to edit a link on the left side of a SharePoint 2013 Standard site. Clicking on Edit Links and changing the link to a desired site and then saving shows error "This operation has timed out. Please try again." and clicking on Quick launch keeps spinning. I have full access to the site.
What could be the cause ?

Answer 1

did You consider using PowerShell as a workaround solution? If something in SharePoint that is OOB and does not work I always consider PS to fix something :).
For Your case something like this may do the trick (example to delete and update):
if ((Get-PSSnapin "Microsoft.SharePoint.PowerShell" -ErrorAction SilentlyContinue) -eq $null)
{
Add-PSSnapin "Microsoft.SharePoint.PowerShell"
}
$SPWeb = Get-SPWeb "[URL]";
$QuickLaunch = $SPWeb.Navigation.QuickLaunch;
foreach($item in $QuickLaunch)
{
$item.Title;
if($item.Title -eq '[quickLunchItemTitleToDelete]')
{
$SPWeb.Navigation.GetNodeById($item.Id).Delete();
}
if($item.Title -eq '[quickLunchItemTitleToModify]')
{
$item.Title = "[NewName]";
$item.Update();
}
}
also I saw You have in site settings link to Quick Lunch. But You may turn on a feature in web to get the more advanced 'Navigation' link and maybe from there You will be able to modify the link You need.
Go to Site settings > Under Site collection admin > Site collection
features
Click Activate in-front of SharePoint Server Publishing
Infrastructure
BUT please be aware that turning on this feature will add also other components to Your which may be not desired.
I hope this will be of any help to You :)
