Hi, 
I have an issue to save imputation for some users, but not all al them.
An Error message appears saying to contact the administrator, when saving the imputation.

The log file says: 
"2022-11-14 10:07:42.777 ===== TRACE ===== WARNING - Left work not retrieved from screen
2022-11-14 10:07:42.777 ===== TRACE ===== - Maybe max_input_vars is too small in php.ini (actual value is 4000)
2022-11-14 10:07:42.777 ** ERROR ** [V10.1.1] ERROR **

2022-11-14 10:07:42.777 ** ERROR ***** [V10.1.1] cause = Error - Maybe max_input_vars is too small in php.ini"
I do not know what this means. Is it a problem of space on servor ?
We are using ProjeQtor V10.1.1,
I would appreciate, if you could help us.
Best regards, 
Romain
