DFFS Install to Form – “URL is not for this web”

[Alexander Bautz]

Hi,

I’m not able to recreate this issue. Can you email me some screenshots of the URL when you get this error message so I can try to recreate it?

Also include the browser you are using.

I sent an email your way.

I think I found the issue, and it’s definitely that “&” not encoding in the url. With the upgrade to SE, the “&” breaks the sub-site’s ability to add web parts to any of its pages. This caused the issue we’re seeing with DFFS not being able to install to forms. Hoping no one would notice I removed it in the url and had no more issues…until I kept getting user emails saying the site was down 😛, so I changed it back which created the web parts issues again.

Did you try my suggested solution (installing DFFS in the subsite and installing it from there)?

Yes, I tried that and it didn’t work. It wasn’t until I removed the “&” that I was able to add web parts again to the subsite and DFFS installed on both the subsite and from its parent site to the subsite. Because it’s an older site created during the 2010-2013 era, the use of the special character ported with no issue. I know the 2016 environment prior to the SE upgrade was iffy with it. SE appears to refuse it.

Also, this site is currently using DFFS from 12+ yrs ago😝. Version 2, before there was a DFFS installer. The rules no longer work with SE, so I’m setting them up on the latest classic DFFS until we eventually migrate to modern pages…where I will look to migrate to modern DFFS 😂.

OK, one option is to manually add the Content Editor Web Parts that loads DFFS to the forms (NewForm, DispForm and EditForm). Just open the form and edit the page and insert a CEWP above and one below and refer a working list to copy the Content Link URL. Set both the webparts as Hidden.

This will “install” DFFS without using the DFFS Installer.

I tried that. The special character interferes with an “under the hood” SP configuration preventing the site from recognizing web parts available in the web part gallery. When trying to add any web parts I get an error stating it has been deleted by someone from the web part gallery. As soon as I remove that special character, the subsite and web parts work as intended. It’s something with the upgrade and policies/limits associated with special characters that no longer retrofit to what was allowed in prior SP versions.
