Clicking on "Reconfigure" TAB we get "Error parsing template....."

When trying to reconfigure F5 settings in Application Services, I click on "Reconfigure" TAB and get the followng:

 

Error parsing template:can't eval proc: "script::run" unable to retrieve TMOS version while executing "error "unable to retrieve TMOS version"" (procedure "iapp::tmos_version" line 8) invoked from within "iapp::tmos_version < 11.4" (procedure "iapp::get_provisioned" line 26) invoked from within "iapp::get_provisioned am" (procedure "script::run" line 3) invoked from within "script::run" line:1

 

Any ideas?
