I keep my installation up-to-date , whenever the update email arrives I go through the update procedure without a problem.
When it arrived recently I was forced to login again.
However this time I get this error.
Error : Form security failed. Please reload the form and check that your cookies are enabled. If you use a proxy server, you must configure Matomo to accept the proxy header that forwards the Host header. Also, check that your Referrer header is sent correctly.
There is no proxy on the webserver side.
I do use a proxy for my browser , but the same error shows even when I switch the proxy off and go direct.
I manually upgraded the matomo installation by downloading the latest zip file , unpacking it , overwriting the current installation and using the commandline to update the database , this all went swimmingly.
Still unable to login though.
Any ideas ?
Thanks.
Mark.
i had this problem also. After deleting all the cookies it worked again.
You can perhaps try to login via an anonymous window in the browser. (ctrl+shift+n)
Hi @PeterM , Thanks for your suggestions.
I have tried both clearing the cookies from my regular session and using a Private Window , both fail as described above.
I have also tried another browser on my laptop which showed the same problem.
Just tried it on my tablet’s browser and I can login without a problem.
So this must be pointing towards the client ?
Intriguing.
Hi @matthieu.
I have gone to the Diagnostics / System Check page , all the green ticks are there.
There were a load of unnecessary files but I have deleted those.
I still see a few warning messages about Archiving , Database Abilities and Geolocation.
I do not use a reverse proxy.
I do have a proxy at the client end but have removed it from my desktop browsers configuration.
Strangely my tablet is still using the proxy and Firefox is the only device that can access the Matomo instance.
On my desktop Firefox (version 70.0) I have network.http.sendRefererHeader = 2
Switched to the Brave browser. Same error.
Tried rolling back to Matomo 3.1.1 with a zip from https://builds.matomo.org/ , this fails as the database has been upgraded to 3.1.2
