Issues after updating to Virtuemart 3.2.1

[alain1]

Hi Folks !
I've got issues after updating....

-In the frontend, all the products appears, but when i click on someone, this message appears "sorry this product have not been found"
I've clear the cache of the browser and the Joomla cache in the backend : no way; nothing change

-In the back end : all the products had disapears...
I've tried to use the database tools "update and optimise the database" in virtuemart : nothing change
I've cleared the cache : no change
I've changed the Languages menu/options : no change
I'v deactivated the cache plugin, the language plugins : no change...

Note : my Joomla installation is up to date, very clean, and very simple : no fancy plugins or hasardous components, mysterious hacks from third party, or something weird hidden in the core code...

What's going on with this "upgrading" ? Upgrading virtuemart is so "randomly" and dangerously surprising...
How to solve theses issues ?

your signature says J3.7..  VM has not been fully tested or released yet for J3.7... maybe this is the problem

you don't say what u upgraded from?  also all VM versions ending in an odd number  are not intended for production sites

any upgrade should be first tested on a site clone in any case so problems can be found and fixed without affecting the live site

i've the same issues with the previous versions of Joomla.
I've made the joomla upgrade after, and all the problems still remains...

So how to downgrade to the 3.2 version ?

I assume just reinstall 3.2.0 - these sub versions are unlikely to have table alterations big enough to affect the previous version .. but test first
