Templates which use {% spaceless %} cause an error in Drupal 10

Thanks @cruno, the patch applies and makes the theme usable with Drupal 10.0.3. I was getting a WSOD on admin pages due to this issue.

patch #2 works on brand new Drupal 10 site, thanks.

I've just installed mediteran 8.x-1.29.
I confirm that patch #2 work on brand fresh install of Drupal 10.1.

Someone can insert this patch in next release after 8.x-1.29 ?

I've lost a lot of time because I had a WSOD :(

Thanks for this!

I have drupal 10, got the same problem, so I applied patch #2 and it worked for me.

Thanks everyone for the help, this is applied to the latest dev and will tag a new release soon
