Hello,

Today I can't access to the configure page, cause by exception  in the attachment.

I supposed that I failed when I managed some plugins, but I can't understand what I did wrong.

After some googling, I see that plugins can be the problem, so I disable ALL my plugins, but I still have the same error.

Could someone give me advice to solve this issue ?

What other information should I provide to help?

FY : Jenkins was installed and updated with yum.
