Custom Locale Plugin disappeared from the plug-in list

Hi everyone,
I think after an OJS update the Custom Locale Plugin disappeared from the installed plug-in list.

If I try to install it, via Plugin Gallery": i search the plug-in and on the right it says “status: Can be upgraded”. When I click on the plug in name, I have a pop up windows saying: Plugin already installed and up-to-date."

This is the installed version of Custom Locale v1.0.0.0 released on 2020-10-13
and this my OJS version:

Someone have any suggestion about how to solve it?
Many thanks in advance,


Hi @Pau,

Are you able to check your PHP error log to see if there are any relevant error messages there?
