Situation that can cause page saving error

Sometimes when we have some programming code on the page, let say we have to submit a programming homework, when we try to save the page, it may say:
"Page cannot be saved due to server error". 

For example, your page have the following content:

  1. text with code like fragment, like "Serial.println(...)"
  2. upload of source codes to page (e.g. .ino)

If the error message pops up, it is possible that Confluence have NOT save your recent work on your page. 

This error is caused by ITS firewall, due to security problem, ITS firewall will filter some programming code related content out in order to prevent any network attack.  

How to deal with the problem

Please try the following steps to avoid the lost of your work:

  1. Copy all the content to any content editor in your local PC.
    Editor example: Notepad, MS word etc.

    This is to ensure even Confluence did not save your work, you can still keep your work, and then paste your work back to Confluence later.

  2. After finishing the backup of your work, refresh the page 

    →     If your work still on the page, try to save the page again
    → If your work disappear on the page, try pasting your work on the page again to see if the problem have fixed

  3. If the saving problem continues, you can choose either way to solve it:

    1. Try to look for the content that caused the error (Time consuming)
      If you have time, try to refresh the page again, then save a blank page (or just remove everything you added this time).
      Then edit the page and paste your content part by part. You should try the save the page when you paste your content each time. 
      When you encounter a part that caused the error again, try to chop down your content into even smaller portion, then repeat the process until you finally found what exact content that caused the saving error.

      Then you can: 
      → Try to replace that content with other wordings
      → If that word cannot be change, it is very important to use the exact wording, then please contact Ho Yee Tung through email ytungho@polyu.edu.hk to ask for help

    2. Include all your code in a text file, then zip it and upload it to Confluence (No time wasting)

      Put all your codes in a new .txt file, then zip your .txt file, and upload it to the Confluence page. 
      In this case, it is not convenience for others to check on your work, but they can still download your zip file and take a look on your code.
