Cannot save Settings after update 4.5

Hello,

I updated from 4.4.7 to 4.4.8 and then 4.5.
When I enter in Master Settings/ Core Settings/ Settings and edit any of the options, after Save , nothing is saved, the initial values are brought back (no warning message).
These values have been reset after update.
It also happens in System or Performance tabs.
It works in Main tab.

In shop log/exceptionlog I find no error. Also no error in apache log or mysql.
This is on localhost, where I test before going live.

Anyone has a clue or where to check for more info?

(by the way, congratulations for new theme).

Thanks

Hi,

did you think of refreshing the DB views? Have you cleared the tmp directory?
What does oxchkversion is telling you? Did the update went fine?
