No blocks available but legacy form.
Now when I try to edit a page and add a block there is no blocks listed at all, except for "legacy Form" in other.
I have tried using a different theme including the elemental etc. no difference.
This is running the latest 8.3.1
Now I seem to have blocks on PHP 5 but not with 7.
My concern now, of course, is how is it going to go on the live server that is running PHP 7.0.25 and the latest updates. Is it a 7.2 prob or 7 in general?
Will have to run some further trials.
I can confirm however that I have absolutely no problem with 7.11
PHP 7.1 works as expected.
PHP 7.2 does have the "no blocks" issue.
