I've read this issue, but I am still unable to resolve this.
I have a Grav website running a clean install of the Gateway skeleton. The skeleton comes with directory system/languages that contains the standard languages files, including en.yaml, which contains:
However, the blogpost sample pages display the date like this: "MONTHS_OF_THE_YEAR[5] 27, 2014" - so it is obviously not picking up this array with the actual names of the month from en.yaml.
It looks like the problem is specific to Gateway. If I copy the blog pages from Gateway to the default Quark theme, dates display correctly, with the name of the month appearing.
@gisle, The pull request from Aug '19 has however not been merged yet...
So for the time being, you will have to fix it yourself. You have 2 options:
Create file '/user/languages/en.yaml' and add the following line:
TXT
MONTHS_OF_THE_YEAR: [January, February, March, April, May, June, July, August, September, October, November, December]
Or, apply the suggested fix in the pull request yourself in '/user/themes/gateway/templates/partials/blog-item.html.twig' by replacing 'MONTHS_OF_THE_YEAR' with 'GRAV.MONTHS_OF_THE_YEAR'.
Note: If you make any changes to a downloaded theme, please be advised that customisations will be lost when updating the theme. Best to use an inherited/child theme and apply changes to the child.
Btw I have updated the post you're referring to and corrected the '/usr' typo's into '/user'
