after updating the Joomla site (hosted on a server with php set to 7.0.18) from version 3.7.4 to version 3.7.5, I found the Radis cache set. I can not disable cache from global configuration, and any value I try to set in global configuration after clicking on the save button, shows error 500 that the system does not support the "radis" cache.
I can not even figure out whether it can depend on Akeeba admin tools or joomla core.
Do you have any indication on this?
Thank you
