I'm new on Joomla. After installation (Joomla5 on Postgresql). I had to search for a template and installed Purity. So far so good. When I launched the site I saw the message to install the t4 framework. According to the documentation from Joomlart I installed the t4-systemplugin_2.4.1. Now the site show a basic purity site but my administrator site isn´t working anymore. Most configuration items give the message : "Call to a member function getGroup() on null" or "Call to a member function removeField() on null" . Any idea what is going on or how to solve it?
Joomla not working after installing T4 system plugin
Thnx for your quick reply.
I don´t see an option to enable debugging. If I try the global configuration I get the error: "An error has occurred.
42883 42883, 7, ERROR: operator does not exist: character varying = integer LINE 3: WHERE "client_id" = 0 AND "home" = 1 ^ HINT: No operator matches the given name and argument types. You might need to add explicit type casts.
If I try to enable the debug plugin, I get the usual message: "Call to a member function getGroup() on null" when I click the Plugins entry on the system dashboard.
I enabled the debug mode and see this error:
42704, 7, ERROR: unrecognized configuration parameter "lc_collate"
It seems to be the issue from Joomla 5 with the Postgresql database, does your server support MariaDB? please try it.
Thanks.
The server doesn´t have MariaDB (yet) running.
I didn´t have problems before I installed the template, so I guess it is somewhere in the T4-system plugin.
I will try to install some other templates before I switch DBs. But first I will write my backup scripts
