I'm getting an error message when I try to upload a new file. What are the new file naming conventions?

As you add new files into Cascade, you’ll start to see a new error message asking you to correct your filename:

An error occurred during creation: The filename must match the following syntax: ^[a-z0-9][a-z0-9_-]*[a-z0-9]\.(jpg|png|gif|docx|doc|xls|xlsx|ppt|pptx|pps|ppsx|pdf|txt|zip)$

File Naming Conventions

  • A filename must be lowercase letters and numbers.
  • A filename may use hyphens or underscores in between letters and numbers, however, hyphens are recommended.1
  • The file types allowed for use in the old web templates (before the responsive template conversion2):
    • Images: jpg, png, gif
    • Word documents: docx, doc
    • Excel documents: xls, xlsx
    • PowerPoint presentations: ppt, pptx, pps, ppsx
    • Adobe Acrobat documents: pdf
    • Homework assignments, lecture supplements (with regard to file types we cannot run on the web server for security purposes): txt, zip
1 Hyphens Versus Underscores

The usage of hyphens versus underscores can affect your SEO ranking in search results. While the algorithm for calculating SEO ranking is complex, researchers tested the difference between these two characters that usually replace spaces between keywords and discovered the following.

Given the keyword sets A, B and C contain any combination of lowercase letters and numbers:

If you search for keywords: A B

  • A file with the name A-B will appear in the results.
  • A file with the name A_B will appear in the results.
  • A file with the name A-C will appear in the results.
  • A file with the name A_C will not appear in the results.

If you search for keywords: A C

  • A file with the name A-B will appear in the results.
  • A file with the name A_B will not appear in the results.
  • A file with the name A-C will appear in the results.
  • A file with the name A_C will appear in the results.

Concluding hyphens allow either keyword to appear in the file name to show up in the results, but underscores require both keywords to appear in the file name to show up in the results.

2 Image File Types in Responsive Web Template

Web maintainers who have worked with us on their responsive web conversion will be more aware of the change in appropriate file types as we won’t be needing gif’s or png’s in the new template. The few that are used are in our logos due to the need for areas to be transparent and overlay other content, while all other images on our website are graphics and photography.

  • gif: These are light files and normally encouraged on the old template to speed up page loading, however, the responsive template requires high quality photography and graphics.
  • png: These are typically heavier files than jpg’s. They would take longer to load and discourage people from viewing our website where they’d be used in the meat of your webpage.
Error Screen pops up after I press Submit on a Page

Click your back button to get back to the page that sent the error and check to see if any of the following exist:

  • Problem: Web addresses that are spelled out.
  • Solution: Change the Web addresses into actual words (i.e., the Scholarship website), and attach a link to it (i.e., the Scholarship website)
  • Problem: Content includes apostrophes (').
    While this is not always the case (noting that the above apostrophe worked), words like W’s will not and will give you the following error:

An error occurred: String index out of range: 3

You may choose to retry the operation. If the problem persists, please contact a system administrator.

The error has been logged to the system console.

  • Solution: Highlight the apostrophe ('), go to the symbol icon, and find the right single quotation mark (’).
  • Problem: Cascade Server is having memory problems.
    You may notice during this time that Cascade is behaving very slowly, but the error (click the image below to enlarge) you are looking for specifically shows this:
    Look for the error: OutOfMemoryError: PermGen space
  • Solution: Contact Web Services about memory problem. This will probably be followed by about 10 minutes of downtime as we restart Cascade Server.
Published a page, but it is not appearing on the live website.
  • Problem: Page is still in the publishing queue.
  • Solution: Go to the "whirlpool" icon on the far left of the blue bar, and click on Publisher then Active Jobs.  You must wait until your page is off the queue.
  • Problem: Not all the pages or files necessary for this particular page were published.
  • Solution: Click on the folder for the website you maintain, then go to the tabs on the right-hand side for this folder and click Publish.  You will often find publishing your entire website resolves both missing page issues as well as speed in publishing.
  • Problem: Your page's System Name has a trailing space, or " " at the end of the name.
  • Solution: Click on the page, then Edit, and then System. Make sure there are no spaces anywhere in the System Name.
Tried to publish a page, but received this message: "Asset is not set to publish. Please enable publishing for this asset and try again."
  • Problem: You may be inside a folder starting with an "_" underscore. Content in these folders is not publishable because they are only pieces of a page, not the whole page.
  • Solution: Find the original page somewhere in your main website folder where this piece is being used and click Publish.
  • Problem: This page is not set to be published. This might be a draft page you originally didn't want to accidentally publish. When you are done with the page, though, you'll want to set it back to be published.
  • Solution: Click on the page, then Edit, and then System. Put a check in the box "Include when publishing".
I see the whole page on Cascade, but when I publish it and look at it on Internet Explorer, part of the webpage is missing.
  • Problem: Microsoft code is somewhere in the page, typically around the point where the webpage breaks.
  • Solution 1: Erase all the content on the page and start over with the recommended process: copy and paste your content into Notepad where your formatting is stripped.  Then copy and paste the stripped text to the CMS and format it accordingly.  Never ever copy and paste from Microsoft Word.
  • Solution 2: Some issues may be hard to clean, so contact Web Services about cleaning up that area of the page.
I see some of my text up against the line on the left (left navigation).
  • Problem: No formatting is placed on the sentence or paragraph.
  • Solution: Click on the text you saw up against the line.  On Format, choose Paragraph. You'll probably not see the difference until after you press Submit and view the page again.
