Cs Cart Not Storing Api Key

Hi.

We have a page on our site which has google maps integrated, there has been an error message on the map for a while now so we checked the API keys and updated the billing details however it is still there.

After speaking to Google tech team they have informed us that it is not saving the new API key on the Cache so when saving it on the admin panel nothing is happening.

Can anyone advise on how to resolve this?

At first, try to delete the var/cache directory manually
