Accidentally put this in the support forum so reposting here...
So I've enabled the Workflow feature in my tiki v.1.8.3 running on apache1.3.31/php4.3.7/mysql4.0.20. I created a new process (called plc_workflow, given version of 1.0), assigned all of the activities and set roles, etc as described in the Galaxia manual linked from GalaxiaWorkflowDoc, and just added code/templates to the activities that only consist of buttons to trigger instance completion ($instance->complete()). And I'm not seeing any errors at the top of the page after I added and saved the code/templates.
2 problems though:
1) From the Admin processes page for the process, I get an error saying that the url was not found when I click on the graph icon.
2) When I log in as a user who can start the process, and click the arrow next to the start activity at the User Activities page, the next page consists of only the following error:
Warning: Smarty error: unable to read resource: "plc_workflow_10/start.tpl" in /www/htdocs/tiki/lib/smarty/Smarty.class.php on line 1149
I noticed an faq at http://tikiwiki.org/tiki-view_faq.php?faqId=11 saying something about clearing /tiki/templates_c to fix the second problem, but all I have in that directory is a README, an index.php file, and an en directory.
Any advice regarding either or both of these problems would be greatly appreciated.
