SharePoint Designer – Error: Could not save the list changes to the server

I was working with a client recently and tried to create a new form for a list within SharePoint Designer and received the unfriendly error:

“Could not save the list changes to the server.”

I had created list forms on this list before, so I began back tracking what has changed since I had created one on this list before.  One thing I did was change a set of Lookup columns within the list to point to new lists and removed the old lists where lookup columns used to point to.

When looking at the list columns I found the lookup column that didn’t have a list that it pointed to:

When you go into the column you will see again there is no corresponding list for the lookup:

I deleted the old column and REFRESHED SharePoint Designer.  If you just try to create the form without refreshing you will receive the same error.

Once I refreshed…Voila!

Hopefully if anyone else gets this error this post will be helpful!

 

Don’t create a SharePoint site with the URL “con”

This might not be news to everyone but this issue was a new one for me. I went to go create a site for a client around the state of Connecticut. I had created multiple other sites using the first 3 characters of the state name; ARI, WIS, etc. So I then went to go create a site with the URL of “con” ……

And then……

Server Error in ‘/ Application with a 404 cannot be found error! At first glance this makes no sense. Your site exists, you can see it in site contents:

I found out that this was due to a reserved words list. This list is not directly within SharePoint, but within the fundamental rules of naming files in Microsoft, regardless of file system. Here are the words that you cannot use as the name of a site, library or list.

CON, PRN, AUX, NUL, COM1, COM2, COM3, COM4, COM5, COM6, COM7, COM8, COM9, LPT1, LPT2, LPT3, LPT4, LPT5, LPT6, LPT7, LPT8, LPT9

If you have created one of these sites you can still delete them through Site Settings -> Content and Structure.

Select your sub site and click Delete.
