What language are you using

Hi, Italian language

I thought so - there was a faulty version of the italian language pack which I believe has now been resolved. Please update the language pack and let us know

i think should have been fixed already in crowdin

anyway as a quick fix #36227

Here's the system info page with error:

while joomla update page states this:

I thought so - there was a faulty version of the italian language pack which I believe has now been resolved. Please update the language pack and let us know

I already have the latest version: https://downloads.joomla.org/it/language-packs/translations-joomla4/downloads/joomla4-italian
Version installed: 4.0.4.1

i think should have been fixed already in crowdin

anyway as a quick fix #36227

Hi alikon, is this bugfix still in dev version?

i think it should be in 4.0.5 as per #36226

I updated to j4.05 before moving to php 8.1 because I already noticed this problem with php 8.0 and j4.x

If I get back to php 7.4 I get no errors.

please check installation/language/it-IT/joomla.ini line 180
should be like this
INSTL_EXTENSION_AVAILABLE="Disponibile %s"

please check installation/language/it-IT/joomla.ini line 180 should be like this INSTL_EXTENSION_AVAILABLE="Disponibile %s"

I got JFIELD_COLOR_SELECT="Seleziona un colore" on line 180 and INSTL_EXTENSION_AVAILABLE="Disponibile %s" does not list into this joomla.ini file :-(

you must look at installation folder

you must look at installation folder

isn't installation folder deleted after installation?

I have a joomla.ini in administration/language/it-IT
with this on line 180 JERROR_ALERTNOTEMPLATE="Il template per questa schermata non è disponibile."

and a joomla.ini in language/it-IT
with this JFIELD_COLOR_SELECT="Seleziona un colore" on line 180.

but no installation folder in joomla.

I searched for that line INSTL_EXTENSION_AVAILABLE="Disponibile %s" in both files without success.

Fixed in #36226
