I am installing a new server with Tryton Ver.7.
But once I have everything installed, I get an error “Incompatible version” in the browser.
The client is not compatible with the server version."
I imagine it’s from SAO, but this happened to me on another occasion and I don’t remember how I solved it.

You must install sao from the same series so I guess it is `7.0`.

This is what I have done:
curl -LO [https://downloads.tryton.org/7.0/tryton-sao-last.tgz](https://downloads.tryton.org/7.0/tryton-sao-last.tgz)
npm install --production --legacy-peer-deps
npm install --legacy-peer-deps
grunt dev

Then you did not install `trytond==7.0`.

If I put the command this: trytond --version
I get: trytond 7.0.6

Are you sure that `trytond` is the one that is actual running?

Check the running processes.

Finally Cédric was the damn browser cache.
This was what happened to me the other time and I didn’t remember it.
Looking around the Forum, here is where it happened to me the other time:

> Hello, I am new to this software and after installing it and trying to connect through the web (SAO), I get an error message of “Incompatible version”. The current versions I have installed of Tryton are: trytond = 6.8.2 tryton = 6.8.1 Do you know where the problem could be?
