Hi,

Admin area also do not work. In that case you have to enable debug mode, in configuration.php file make those changes - then you will see what is wrong.

And I am not sure, if you checked on our site BEFORE J! upgrade, but Resort template was built for J3 and J4. There are big changes in Joomla 5 Core, so some part of "old" code can may not work anymore.

I did please check

any news??

you have problem with plugin from solidres component:

plugins/system/solidres/solidres.php

probably old version, not updated. Or that extension do not work with Joomla 5!

Rename folder /plugins/system/solidres and it may work after.

As you see it's not our extension. Solidres has its own support (link below).
