Check your cache folders for error logs (blank page = error). You are getting errors because your install method is causing problems.

As has been posted in this thread several times you can't keep originals and backups together. (there's actually a fairly extended conversation on this very subject with someone who like you had errors after installing Edit Orders -- a quick search of this thread would have turned up this very post and the follow-up advice given)

Keep your backups OFFLINE and load ONLY the files needed to run the mods.. You are getting errors because your renamed original files are interfering with the ones required by the module. In other words unless the install instructions say to do this, DON'T. It's a bad habit to get into, and as you have discovered causes issues..

If you want to back up your store file in case you need to rollback when installing modules, do a proper backup of your store.

I am having some issues with this Modification. I have Super Orders 3.0 installed and works great (thank you). However I wanted to take it further by adding the Edit Orders 3.0 to my site. I modified all folders per instruction as well as merged mod files with current files on server using winmerge. No problems there. I also saved copies of the unmodified files on server by renaming the originals to filename_ORIGINAL.php. After uploading all files and folders to my site, when I tried to access the admin section I received an HTTP 500 error in IE8 and in FF I got a blank screen. So I went and removed all files that were uploaded, renamed originals and all worked again. I then uploaded one file at a time and check my admin section after each file and found that the file common_orders_functions was the problem so far. I know on line which has this code -
Code:
'" .zen_db_input($comments)  . "')");
is different then what is on my server and mine is
Code:
'" . $comments . "')");
I am not sure why this is causing me not able to access the admin section at all even for log in, but it is. I have searched for my issues and am unable to find anything related to this.

Zen Version 1.3.9h
Site hasn't been upgraded
Addons are Super Orders 3.0 and other not related to the ordering system.

Thank you for your time and understanding as well as your help.
