My client records are no longer open

Hello

I have a message that blocks the opening of my windows
“There was an error processing your request, please try again later.”

“If this error persists, please ask your administrator to disable Ajax for this module”

How do I disable Ajax for the module?

Thank you

Can you please give more information? For example, can you give the steps you took before you saw this message? What version of SuiteCRM are you using?
