Item9882: Extender.pl failing when Installing e.g. ldapcontrib because of error reported from installed CounterPlugin

Hi, i'm trying to install ldpacontrip and i've got this message error :

Could not load /var/lib/foswiki/tools/extender.pl

There was a compile error: Argument "15 (Main,WebHome)" isn't numeric in addition (+) at /var/lib/foswiki/lib/Foswiki/Plugins/CounterPlugin.pm line 57.

BEGIN failed--compilation aborted at /var/lib/foswiki/tools/extender.pl line 147.

Error when trying to eval the file content: This installer must be run from the root directory of a Foswiki installation at (eval 172) line 112.

BEGIN failed--compilation aborted at (eval 172) line 147.

Thank you for your help

What version of Foswiki are you on? I cannot make the line 147 make sense in a 1.1.0 context. If you are on an older version then please upgrade because we do not fix old versions.

There is still a fix to be done on CounterPlugin. Ldap plugin is not the problem

Code has changed so significantly over the past 5 years, setting this to "no action" ... please open a new task if the problem still exists.
