Module builder does not save new field

It happened very often when the rights in a Linux system were not set correctly but the time this happened in one of my systems it was by an upgrade which set the OPCACHE directve.

See rthe already mentioned post https://sugarclub.sugarcrm.com/dev-club/f/questions-answers/1088/field-in-custom-module-doesn-t-save for all possible explanations. If this happend sewly I would suppose the OPCACHE is the reason why it happens.

Not being a Linux expert, can you advise if the solution to disable opcache should only be temporary whilst developing, but be switched back on for production?

I realise that ideally we'd all have a staging server with opcahce always disabled.
