logged in as another customer

[musicmaster]

It may have been asked before but as Prestashop still doesn't index the forum I see no alternative but asking it again.

 

I found myself suddenly logged in as another customer when visiting my webshop and I wonder what could have caused that undesirable behavior. It means that other customers may get into each other's account too.

 

Yesterday I had added "query_cache_type = 1" to my.cnf and I am wondering if that might have caused the problem.

some time ago, for prestashop 1.5.x we had a lot of topics related to similar thing.

the problem was related to caching: for example: https://www.prestashop.com/forums/topic/247284-user-info-block-caching/

 

in your case, i bet, the problem was the same. Especially if you use some other than default "cache" features.
