Hi Florianbfr,

I looks like something did not work well during the update to the 2.10.2 version.

Can you please first try to execute the Tools / Maintenance / Repair tools of your Piwigo server?
I you then still face the issue, please try to uninstall some plugins.

Cheers

Yes, try to repair your database. I also suggest that you search for posts in this forum talking about issues encountered after updating Piwigo to 2.10.x.

The error message "unacceptable content-type : text/html" suggests that your server does not return a Json answer to the iOS app as it should. If your server is available from the Internet, can you create an account giving access to a non private albums and send me the link so that I can have a look with a debugger?

Hello,

OK, my trouble is solved !
your expertise was very relevant and guided me towards the solution.
As my server run on YunoHost solution (self hosting) since the last update to acces to the PIWIGO gallery from IOS or ANDROID I must install PIWIGO with the option "public access" activated.

Now it works perfectly !

Tanks you
Florian
