[pmwiki-users] Parameter must be an array or an object that implements Countable

[Petko Yotov]

Yes, for older PHP versions, or for older PmWiki installations that 
cannot upgrade, you can edit forms.php and insert @ before the second 
count() on this line (line 109 for your version, may vary for others):

   while (count($posnames) > 0 && @count(@$args['']) > 0) {


PmWiki 2.2.0 to 2.2.106 also have this problem -- before PHP 7.2 this 
was not a problem.

This was reported by DFaure a few weeks ago and fixed in Subversion for 
2.2.107 but I wanted also to include some hooks and fixes suggested by 
ChuckG before releasing 2.2.107 but could not find the time.

I'm releasing 2.2.107 today and will work on the hooks for the next 
version.
