I've just upgraded a site to 1.5.8a and it was working fine locally on my computer.

The site has been put in a live environment on PHP 8.1. Now it is throwing up a huge amount of language file errors similar to this. There are too many errors to post them all here.

Your errors reference: languages/english/meta_tags.php

The new php naming convention for the language files is:
lang.meta_tags.php
Additionally, the php structure in these files has been changed.

Your errors MIGHT be a consequence of the above.

The errors logged are a consequence of the above. See this (https://docs.zen-cart.com/dev/plugins/language_files/) zc158+ language-loading documentation for additional details.

In particular, see the guidance in

https://docs.zen-cart.com/user/local...ustomizations/

If your pre-158 cart has a large number of language file overrides, it may be easier for you to just start fresh with the 1.5.8 language files and apply a minimal set of customizations.

I think I have sorted all the language file errors out, but now I am getting this.

it would seem you have a problem with this file:

/Applications/MAMP/htdocs/MYSITE/includes/templates/MYSITE/common/html_header.php

i would compare that template file to the template file here:

https://github.com/zencart/zencart/b...tml_header.php

it would seem you are missing some crucial elements from that file, starting with this group:

best.
