SharePoint not finding linked aspx files.

Question

SharePoint not finding linked aspx files.

Daniel Nuttall 0

Hi All

I have started to have an issue with my links in a SharePoint (Edu) site not being found. The SharePoint site holds quite a lot of SCORM content packages which using PowerShell i have converted in to aspx files.
I upload the package in to "Site Contents -> Site Assets", i then add a quick link and navigate to the file within the site assets folder, i set it to open in a new tab and republish.

When i select the link the tab opens and i get the attached "file not found" message.

Any files i have uploaded previously all still work fine and as expected, it's only affecting new files that i try to add to the site. does anyone have any ideas how i could resolve this? I have checked site permissions, ruled out firewall issues and tried uploading the launch file to a folder that isn't so deep on the folder hierarchy.

At a loss :/

Could this be caused by a bug in custom scripts allowal?
The docs says existing .aspx should work without problems but you cannot upload

Hello @Daniel Nuttall

From your description, it appears that you are experiencing an issue when adding a Quick Link to a SharePoint site, where the link does not open the ASPX file as expected, even though the correct URL is being used.

To help me investigate this further, could you please share a screenshot of the Quick Link settings you have configured? In addition, please send me the URL that appears when you add the Quick Link (this can be found at the top of the page) and try to access the link before adding. Kindly share these details via a private message.

I sent you a private message, please click the button shown as below to access your Private Message.

I look forward to your response and will be happy to assist you further once I have this information.

OK, it was about the custom scripts deny https://learn.microsoft.com/pl-pl/sharepoint/allow-or-prevent-custom-script#identify-sites-that-allow-custom-scripts

Hello Dłuski Tomasz

Thank you for reaching out.

From the article (Change custom script settings for a SharePoint site), the upload option will not work when the Custom Scripts feature for the SharePoint site is set to Blocked instead of Allowed as the screenshot below:

To upload an .aspx file successfully, the Custom Scripts setting must be enabled. You will need to contact your IT administrator to allow Custom Scripts for the site. Please note that once enabled, this setting will automatically revert to Blocked after 24 hours.

Hi @Nam-D

Apologies for late reply, i have had to wait for the SharePoint admin to come back to me on a few things and authorise me to share some images and URL's etc.
First i will have them check to see if the Custom Scripts is still allowed and not blocked. once confirmed i will come back and go from there.

Thank you for the reply and support.
