Help - 500 Error

[sgt_slaughter]

Currently I'm getting a 500 internal Server error when going to my Catalogue page (the admin page works fine). I've installed the debug plugin and it is showing the following error:

[30-Aug-2009 11:34:22] PHP Fatal error: Call to a member function Execute() on a non-object in /<path>/includes/classes/currencies.php on line 31

Here is the following changes that lead up to the issue:

1) Installed 1.3.8a security patch (although this is an admin only - The admin page is working fine after this and it is showing properly).

2) Changed Admin directory name (also changed configure.php to reflect changes - admin page still working).

3) Setup SSL certificate (with my host domain they required that I have my domain setup as my primary - which required me to move some directories, including the zencart directory).

4) I made the changes in the includes/configure.php file, changed permissions so I could write via ftp, uploaded the file. The site worked (although showed warning at top of page telling me to restrict access to includes/configure.php). I chmod to 444 and then my page started showing blank. (Tried to reverse change and it is still blank).

The only Add-ons I have installed are:
Beanstream payment module
CanadaPost module
Debug module

My php version is: 5.2.9 (I don't believe this has changed since my initial setup)

I've barely done any customizations, I'm still in the setup phase as I haven't gone live (although I was almost done setting everything up).

Any help would be greatly appreciated.

Thanks!

Figures, I post a message and figure the solution out 10 minutes later...

Anyways, for people having similar issues, I was using Filezilla as my FTP client to make my FTP permission changes. For some reason the directory /includes/init_includes had lost all permissions (I was unable to change permissions through filezilla & Windows Explorer). I logged onto my provider and used their file manager to change the permissions and everything started working again.

Anyways I guess if your seeing similar issues, check permissions on all your files.
