Cannot update text for js.composer.error.post_length

I’m trying to update text for js.composer.error.post_length. Experiencing this on 2.9 and 3.1.0.beta2, on production, staging and in my local environment.

On FE it shows [missing {{min}} value] although value has been set.

Error log says:

NoMethodError (undefined method `scan' for {:one=>"Post must be at least %{count} character", :other=>"Post must be at least %{count} characters"}:Hash keys = text.scan(pattern) ^^

NoMethodError (undefined method `scan' for {:one=>"Post must be at least %{count} character", :other=>"Post must be at least %{count} characters"}:Hash

    keys = text.scan(pattern)

That string was changed back in 2021. It uses %{count} instead of %{min} and has been converted into a pluralized string (one, other).

You can fix your customized string by going to Customize → Text:

  • Search for “js.composer.error.post_length”
  • click “edit”
  • click “revert changes” and confirm the question with “yes”
  • click “back to search”
  • Search for “js.composer.error.post_length”
  • You will see 2 results, customize both strings if you wish

I wonder, could we build error handling that falls back to English in these cases and logs something?


For some reason I couldn’t get this to work, the confirmation dialog was not opening because JS error ‘get_attributes’, the dialog element was null.

But then I turned the safe-mode, check if it was working and everything was updated automatically. I turned off safe-mode, went back to my theme and again, all was working as intended.

So safe-mode fixed it I guess. And there is no more JS error mentioned above. (Should have tried with safe-mode in the first place, smh).

Thanks for your help!
