Theme development

I set specific node for 403 and 404 error as /node/5 and it works for regular urls like example.com/sitesdfgf, but when request example.com/sites or example.com/privatefiles shows default server 403 page

Im using Metatag module and there isnt any field for meta title. currently I use default content title for pages that shows in tab bar, but i need different value for meta title. I need 1 word title for tab bar as page title and a sentence for meta name as <meta name="title" content="a sentence here"> but only have page title, description, keywords and abstract in module configuration

After submit new update on /admin/config/regional/content-language get blank page and if return to page again no changes happend, i rebuilt cache and try again but cannot submit new change

It could be about paragraph? previous paragraph field working fine with enabled fields correctly but new changes impossible.

I think it related to count of paragraph fields and after using a number of fields it cannot add new data or store new update, could be correct?

Hi

I am using the commerce-price-calculated.html.twig file to format the currency (by telling it in config to not show any symbol nor code)

And it works per plan currency, because there the twig has the "currency" variable available, as I guess it's in commerce_price.module.

But sadly the commerce-price-calculated.html.twig does not have access to that variable.

I am trying to use .theme file preprocess to give access to the currency variable for the commerce-price-calculated.html.twig but I can't seem to figure how the main line of code would like like.

I want to filter post based on the year, so used Content: Authored on (grouped) and tried to find a way to collect all related posts but seems everything should be complicated in Drupal as usual!
