Hello,

I'm having some issues with using prestashop in the back office, from time to time I have these errors (only on the back office) (see attached picture)

here is the full message :

 

Whoops, looks like something went wrong.

The PID is changing and is not the same every message I get

 

I found this that could help : https://stackoverflow.com/questions/30753674/error-while-sending-query-packet

Since I'm not sure I don't want to meddle with things that could worsen the situation.

Any suggestion is welcome

Thanks
