I just ran into a problem, that I don’t know where it comes from, but that appeared after upgrading to 3.5.
I’m in the context of a Uniform controller, where submitted values are escaped. I now find an error:
Class 'Laminas\Escaper\Escaper' not found
…/kirby/src/Toolkit/Escape.php : 87
I thought that it was a Composer issue (I had Kirby as a submodule), but even after I ran composer install, I still have the error. NB: I’m testing on a MacOSX install of PHP 7.4.8, (compiled with ctype).
Quite standard, I think (like the old starterkit – I didn’t checked the new one) :
assets
content
kirby
media
site
…
plugins
controllers
…
But I’m not sure I understand your question. I was wondering if my problem with Escape class was coming from the git/submodule setup (or if I needed to run composer –which I’m not used to).
The Laminas class is inside /kirby/vendor, check if that folder exists. I suspected you might have an extra vendor folder in the project root, but if that is not the case.
