User is not able to access Case from Support Central. Getting error “Error: Error occurred while loading a Visualforce page”

Hi All,

I am getting an error while accessing the Case from the support central portal  “Error: Error occurred while loading a Visualforce page”.

Please find te below screen shot for the reference:
User-added image

I checked below things for this:
1. total size of attachments on case is within 10Mb
2. I see ‘Description’ field on Case Detail page was too long.

Will it be the reason  behind this? If then what we can do to achieve this?

Welcome to your suggestions!

Thanks in advance!

Are you passing any Id?

Try passing id like this> in your URL after /apex/vfpagename?id='any valid account id in your org here'
