Weird cache error in BO.

[cwms]

Hi,

 

We are using Prestashop 1.7.2 and we changed database server. Everything was pretty easy (just had to change details in /app/config/parameters.php) and it was smooth.

 

I've cleared the cache in BO and it seems to be working fine when i test the front end and backend.

 

But, when i'm in the BO on the page Catalogue/products, it get this weird error (the previous db server is off). Why ? Any other cache we should clear ?

 

 

 

ConnectionException in AbstractMySQLDriver.php line 103:An exception occured in driver: SQLSTATE[HY000] [2002] Connection refused

 

 

Followed by a lot of errors including the previous server, db, login & password ...

The error appear only in debug mode. So, i assume that the DEV cache is not cleared ? If so, anyone knows where the DEV cache folder for the BO is ?

Only rename or delete \app\cache\dev folder. Then refresh the BO page, the folder "dev" will be restored and this will fix your issue.
