Renaming or moving Cerb4 to a different URL (Clearing the cache)
From Cerberus Helpdesk Wiki
[edit] Why move the Helpdesk?
If I need to change the /cerb4/ directory to /support/, can i just rename it? Or, I need to do any other things?
This question comes up way more often in the forums than I’d like to admit. But it’s definitely a good question as there’s a number of good reasons people need to change the install path — everything from not liking the default cerb4/ directory, to downloading the Helpdesk to the wrong location. A perfectly acceptable excuse I’ve heard in the past from Administrators, is they were trying out the software on a temporary (private) URL and now want to put Cerb4 into production somewhere else.
So if you need to change the root directory from ‘cerb4′ to ‘helpdesk’,
e.g. “example.com/cerb4″ to “example.com/helpdesk”,
or move the install to a simpler URL,
e.g. “example.com/helpdesk/cerb4″ to “example.com/cerb4″
there are a couple things you need to do after you reorganize your file structure.
[edit] Clearing the cache
Start by deleting the following files in the Cerb4 folder:
- storage/tmp/zend_cache*
- storage/tmp/templates_c/*.php (These are the “junk” files that start with the encoded-looking names, e.g. %%F5^F51^F51A97AC%%)
- Note: If you see any dot files, like .svn or .gitignore, you can leave them alone.
[edit] Verify Community Portals and Worker RSS feeds still function
Just to be safe, check and see if you are experiencing any problems with features that might be generated off a relative path. This includes your Community Portals or Worker RSS feeds, found under ‘helpdesk setup’, ‘Community Portals’ and ‘my account’, ‘RSS Notifications’ respectively. Try regenerating any Community Portal index.php files by saving changes and copying the files again to the appropriate (new?) web path where you deploy your public portal. And the RSS feeds by again clicking the relevant orange RSS icons 
in your worklists of choice and deleting the old ones in the ‘RSS Notifications’ tab.
- Also note that clearing the cache may help with general troubleshooting. So if you ever find yourself staring at a blank page when trying to load the Helpdesk, this is a good first step to take.
