Dear, we are on ispconfig latest versione on master-slave configuration. My request here is just related to an initial debug source. Basically this happen only certain customer on only certain slave server. If the customer (that he has the right to do the modification) try to modify something on a webhost (something like active let's encrypt or change php version), the master panel don't reply anything after that the submit button is pressed. Just nothing happen: no job inserted in queue, no error reporting. Nothing. I know that i can debug the cronjob, using the normal debug mode. But how can debug something like that inside the interface? The customer has the right to do that modification, and if I try to do it as administrator, i have no problem to complete them. Any clue or any ideas on where can I start to debug? thank you.
